In the WordPress Block Editor, open the page, place the cursor where the image belongs, choose + → Image (or type /image), then upload a file, select one from the Media Library, or insert an image URL. Review the image’s alternative text and presentation, then save or publish the page. The exact buttons can differ with your WordPress version, theme, and site configuration.

First, identify which editor your site uses

WordPress sites commonly use either the Block Editor or the Classic Editor. The instructions are different:

  • Block Editor: you add an Image block.
  • Classic Editor: you place the cursor in the editor and use the Media Uploader.

If you see blocks, a block inserter plus button, or a slash-command menu, use the Block Editor instructions below. If you see a single formatting toolbar above a large text area, use the Classic Editor section.

Add an image with the WordPress Block Editor

1. Open the page and choose the insertion point

  1. In your WordPress dashboard, open the page you want to change for editing.
  2. Click in the content at the position where the image should appear. You can use an existing Paragraph block or create a new one.
  3. Save the page as a draft while working if you do not want changes to be public yet.

2. Insert an Image block

You have several documented ways to create the block:

  • Click the top-left + Block Inserter, search for Image, and select it.
  • Type /image in an empty paragraph and press Enter.
  • Drag an image onto a blank page or an empty Paragraph block.
  • Open the inserter’s Media tab and choose an available image source.

After the block appears, WordPress presents choices such as Upload, Media Library, and Insert from URL.

3. Choose where the image comes from

Upload a file from your device

Choose Upload, select the image file on your computer or mobile device, and wait for WordPress to add it to the page and Media Library. This is usually the most reliable option because your site stores a copy rather than depending on another website.

Reuse an image in the Media Library

Choose Media Library, search or browse the existing files, select the image, and confirm the selection. Reusing a library item avoids creating another copy and lets you use its stored metadata as a starting point.

Insert an image from a URL

Choose Insert from URL, paste the complete image address, and press Enter. The image remains dependent on that external address. If the owner moves, deletes, or stops sharing the original, your page can show a broken image. Use this route only when you have permission to use the image; WordPress’s guidance is, “Only use images you have permission to use.”

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use an optional Openverse source

If your site shows Openverse in the Media tab, you can select an image there. Availability depends on theme support and site configuration. An image added from Openverse is automatically saved to your Media Library.

4. Set alternative text before publishing

Select the image and find the Alt text field in the block settings. Write a concise description of the image’s purpose, not a list of keywords. For example, “Three-column pricing table for the business plan” explains a meaningful chart better than “business pricing image.”

If the image adds no meaningful information or functionality and is purely decorative, mark it as decorative when that control is available. This allows assistive technology to ignore it. Do not mark an image decorative merely because it is attractive; decide based on what a reader needs to understand or do.

5. Add a caption or adjust presentation

The Image block toolbar and settings can expose controls for:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Adding, editing, or hiding a visible caption beneath the image.
  • Aligning the image within the content area.
  • Changing the displayed size or choosing an available resolution.
  • Resizing with handles.
  • Cropping, replacing, or linking the image.
  • Making the image enlarge when a visitor clicks it, if your editor and theme provide that option.

Use a caption when readers need context that should be visible to everyone. Keep the alt text focused on the image’s purpose; a caption and alt text do not have to be identical.

6. Save, preview, and publish

  1. Use the editor’s normal Save draft, Update, or Publish control. The label depends on the page’s current state.
  2. Preview the page at the site’s available screen sizes.
  3. Check that the image is in the intended position, the caption is readable, and the surrounding text still flows correctly.
  4. Open the published page in a private browser window if you need to verify what a visitor sees.

Which insertion method should you use?

Method Best for Main dependency or risk
Upload A file you own or are licensed to use Requires a local copy and permission to publish it
Media Library An image already uploaded to this site Uses the selected library item and its metadata
Insert from URL An image that must remain hosted elsewhere The page can break if the external file moves, is deleted, or is no longer shared
Openverse (when available) Finding a permitted source through the Media tab Availability depends on theme support and configuration
Gallery block Several related images Requires selecting multiple Media Library items rather than separate Image blocks

Alt text, captions, and Media Library metadata

Block alt text versus Media Library alt text

Alt text entered in the Image block applies to that particular page or post. Alt text stored in the Media Library is the default used when the image is inserted elsewhere. This means you can describe the same image differently when its purpose changes—for example, as a product detail on one page and as a decorative background on another.

Media Library details such as title, caption, alt text, and description can also make files easier to find and can support accessibility and search optimization. Review the wording before reusing an old image whose original context is different.

When to use a caption

A caption is visible text beneath the image. Use it for a source credit, explanation, date, or other context that all visitors should see. If the information is needed only by someone using assistive technology to understand the image, put it in alt text instead.

What happens when you crop

Cropping in the media editor saves the edited version as a new image file and leaves the original in the Media Library. This lets you preserve the source while using a different composition on the page.

Add an image with the Classic Editor

  1. Open the page for editing and place the cursor where the image should appear.
  2. Open the Media Uploader from the editor toolbar.
  3. Upload a file or select an existing item from the Media Library.
  4. Review the available image details and insert the item into the content.
  5. Save or publish the page using the normal Classic Editor controls.

Do not look for an Image block in this interface. If you need block-level alignment, responsive behavior, or gallery controls, confirm whether your site can switch to the Block Editor before changing the page.

Add several images as a gallery

For a group of related images, use the Gallery block rather than adding many unrelated Image blocks. Open the block inserter, choose Gallery, and select uploaded or existing Media Library images. Arrange the items in the gallery and review its presentation before saving. A gallery keeps a set of images together and gives the editor controls intended for multi-image content.

Troubleshoot common image problems

The Image option is missing

You may be in the Classic Editor, inside a block that does not accept an image, or using a restricted editing role. Return to a Paragraph block and try /image, or open the top-left Block Inserter. If there is no block inserter at all, follow the Classic Editor workflow.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The image is not visible after inserting a URL

Open the image address in a separate browser tab. If it no longer loads, the external file was moved, deleted, or access was revoked. Replace it with an uploaded copy or a current URL for which you have permission.

The image appears in the editor but not on the public page

Preview or publish the page and check again. A theme’s CSS, a visibility setting, or a page-specific layout can affect the front end even when the editor preview looks correct. Replace the image block if it is empty, then save and reload the public page.

The wrong alternative text appears

Select the image on the affected page and edit the block’s alt text. Remember that block text applies to that page, while Media Library text is the default for future insertions elsewhere. If the image is decorative, use the decorative setting rather than leaving a misleading description.

A pasted image disappears later

When you paste an image from another document, WordPress may upload it to the Media Library. If the toolbar offers Upload to Media Library, use it to save a copy. Otherwise the page may depend on a temporary or externally hosted image that can stop working.

The image is too large, too small, or poorly framed

Select the image and try the available size, resolution, alignment, resize, or crop controls. If the original composition is unsuitable, replace it with a better source rather than forcing extreme dimensions in the editor. Check the result on both a wide and narrow screen because the theme controls the final layout.

Or skip the browser setup

ScreenshotNeo is a website screenshot API and MCP server. It does not insert an image into WordPress, but it can capture a visual check of your published page after you add one. A single GET request returns a PNG, JPEG, WebP, or PDF. Before capture, it accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each step can be turned off. Bot checks, CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and the response identifies the page verdict and billing status in headers.

Use the API examples in the ScreenshotNeo documentation after replacing the URL with your published WordPress page.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com/your-wordpress-page/ -o shot.webp
import requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://example.com/your-wordpress-page/"}, timeout=90)
open("shot.webp", "wb").write(r.content)
const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://example.com/your-wordpress-page/' }); const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);

ScreenshotNeo also offers an MCP server with take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients. The Free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots. Create a free ScreenshotNeo account to check your page without setting up a browser script.

Final checks before you publish

  • You have permission to use the image.
  • The image is inserted through the correct editor for your site.
  • Alt text explains meaningful content or the image is correctly marked decorative.
  • A caption is present when visible context or credit is needed.
  • An externally hosted image is stable, or you uploaded a copy to the Media Library.
  • The page has been previewed at the intended size and saved or published.

Frequently Asked Questions

Can I use the same image with different alt text on different pages?

Yes. Alt text entered in an Image block applies to that page or post, while the Media Library version is the default used when the image is inserted elsewhere.

What should I do if I need to add many related images?

Insert a Gallery block and select the images from the Media Library instead of creating a series of unrelated Image blocks.
