Put a PNG on an HTML page with an <img> element and set its src attribute to the image’s reachable path or URL:
<img src="images/photo.png" alt="A red kite flying over a field">Use a relative path for a file in your site, or an absolute https:// URL for an image hosted elsewhere. Add useful alternative text and known dimensions, then use srcset or picture only when you need responsive sizes, viewport-specific sources, or format fallbacks.
The basic PNG image element
The HTML img element embeds an image. Its src value identifies the image URL or path; at least one of src or srcset is required. The element is a void element, so it has no closing tag. See MDN’s img reference for the element’s current attributes.
<img src="images/photo.png" alt="A red kite flying over a field">The browser requests the value in src. The PNG must be available at that address; placing a filename in HTML does not upload or copy the file.

PNG beside the HTML file
<img src="logo.png" alt="Company logo">This works when the page and logo.png are in the same directory.
PNG in a child directory
<img src="images/logo.png" alt="Company logo">If your page is in the project root and the file is in a sibling images folder, use the folder name followed by the filename.
PNG in a parent directory
<img src="../images/logo.png" alt="Company logo">.. moves up one directory from the page’s URL location. Add another ../ for each additional level, but prefer a predictable public asset folder in larger projects.
PNG at an absolute URL
<img src="https://example.com/assets/logo.png" alt="Example company logo">An absolute URL is resolved independently of your page’s directory. Use a URL that visitors can reach; a path such as C:UsersSamPictureslogo.png points to your computer, not to a file on a public website. MDN explains relative and absolute image URLs in its HTML images tutorial.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteHow relative paths are resolved
A relative src is resolved from the page URL, not necessarily from the folder you currently have open in your editor. For example, if the page is served as https://example.com/blog/post.html, images/photo.png normally requests https://example.com/blog/images/photo.png. Moving the HTML file or changing the server’s URL base can therefore change which file the browser requests.

- Identify the URL of the page in the browser.
- Start at that page’s directory when writing a relative path.
- Match every directory, filename, and extension exactly.
- Open the resulting image URL directly in a browser to confirm it is reachable.
Servers commonly treat capitalization as significant. Photo.png, photo.png, and photo.PNG may be different files. Keep the path URL-friendly and avoid relying on spaces or unusual punctuation.
Write alt text that helps people
The alt attribute is the image’s text alternative. Describe the image’s meaningful content or purpose in the page’s context, rather than repeating a filename or writing “image.” The MDN image guidance covers alternative text and image dimensions.
<img src="images/kite.png" alt="A red kite flying over a field at sunset">For an image that conveys information, include the detail a reader needs. If the image is purely decorative and its purpose is already conveyed elsewhere, use an empty alternative, alt="", so assistive technology does not announce an irrelevant filename. Do not omit alt accidentally: decide whether the image is informative or decorative.

Reserve space with width and height
When the intrinsic dimensions are known, include both width and height:
<img src="images/photo.png" alt="A red kite flying over a field" width="1200" height="800">These attributes describe the file’s intrinsic dimensions. The browser can reserve the appropriate space before downloading the image, reducing unexpected layout movement. CSS can still control the displayed size:

Choose the right markup for one or many PNGs
One fixed image: use img
A single PNG at a known URL needs only img, with alt and dimensions when applicable.

Several resolutions: use srcset and sizes
When you publish multiple widths of the same image, srcset gives the browser candidates and sizes describes the expected display slot when you use width descriptors:
<img
src="images/photo-800.png"
srcset="images/photo-400.png 400w,
images/photo-800.png 800w,
images/photo-1600.png 1600w"
sizes="(max-width: 600px) 100vw, 800px"
width="1600"
height="1067"
alt="A red kite flying over a field">The browser chooses among the candidates. Keep the ordinary src as a fallback for clients that do not select a srcset candidate. Ensure every listed URL exists; a typo in one candidate can produce a broken image at only some viewport sizes.
Different conditions or formats: use picture
Use picture when the source should change for a media condition or when you want to offer another image format. The nested img remains the fallback:

<source media="(max-width: 600px)" srcset="images/photo-crop-small.png">
<source type="image/webp" srcset="images/photo.webp">
<img src="images/photo.png" alt="A red kite flying over a field" width="1600" height="1067">
</picture>The MDN image-format guide describes format selection. Keep the fallback img valid because it is the image used when no source matches or a format is unsupported.
Keep a PNG from overflowing its layout
HTML attributes provide intrinsic dimensions; CSS controls presentation. A responsive rule prevents a large PNG from exceeding its container:
img {
max-width: 100%;
height: auto;
}Scope the rule to a class if other images on the page need different behavior. Do not set only a new width while leaving a fixed, unrelated height; that can distort the image. Using height: auto preserves its aspect ratio.
Test the path before debugging the markup
- Save the HTML file and make sure the PNG is inside the directory served by your web server or development tool.
- Copy the exact value of
srcand open it directly in the browser. - If the direct URL fails, correct the directory, filename, extension, or capitalization before changing HTML.
- If the direct URL works, inspect the page’s resolved request in browser developer tools and compare it with the working URL.
- Check the page over the same protocol and host visitors will use; an image available only on your local computer is not a deployable asset.
Troubleshoot a broken PNG
The image icon appears, but no picture loads
- Check the relative path from the page URL, not from your editor’s workspace root.
- Confirm the file exists at that URL and that the extension and capitalization match.
- Open the image URL directly. A not-found or access response identifies a hosting or path problem.
- Look for an empty
srcor a typo introduced while editing.
MDN lists empty sources, inaccessible data, corrupted files, and unsupported formats among possible causes of image failures; see the img troubleshooting notes.
The image works locally but not after deployment
Deployment often changes the page URL, directory structure, or filename case. Check the deployed page’s source URL and request the deployed image address directly. Upload the PNG to the site’s publicly served assets instead of referencing a local filesystem path.

Only some responsive images fail
Test each URL in srcset and each matching source in picture. A valid fallback does not repair a missing candidate that the browser selected. Also verify that the sizes expression describes the actual layout slot.
The file is present but appears corrupted
Try opening the original PNG in an image viewer and re-exporting it if necessary. A damaged file or problematic metadata can fail even when the URL is correct. Replace it with a known-valid PNG and retest the same markup.
When an automated screenshot is easier
If your goal is to capture a rendered page containing the PNG rather than hand-author an img tag, ScreenshotNeo can return a PNG, JPEG, WebP, or PDF from one GET request. It accepts consent banners before capture and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each cleanup step can be disabled. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and response headers identify the page verdict and whether the request was billed.
Or skip the browser setup
Use the ScreenshotNeo API with an access key. The API documentation lists all options, including full-page capture, lazy-image loading, CSS-selector element capture, dark mode, device presets, retina scale, PDF settings, custom CSS or JavaScript, clicks, waits, blocked resources, headers, cookies, user agents, authorization, timezone, geolocation, transparent backgrounds, resizing, caching, signed links, asynchronous webhooks, bulk capture, and usage data.

Practical checklist
- Use
<img>for a single PNG. - Set
srcto a reachable relative path or absolute URL. - Write contextual
alttext, or usealt=""for purely decorative artwork. - Include the real intrinsic
widthandheightwhen known. - Add
srcsetandsizesfor multiple resolutions. - Use
picturewith a valid fallbackimgfor media or format choices. - Open the resolved image URL directly when debugging.
Frequently Asked Questions
Does an img element need a closing tag?
No. img is a void HTML element, so write its opening element and attributes without </img>.
Can I reference a PNG that is not in my HTML file’s folder?
Yes. Use a relative path such as ../images/photo.png or a reachable absolute URL. The relative path is resolved from the page URL.
What should I do if I have only one PNG size?
Use a normal img with its src, meaningful alt text, and intrinsic dimensions when available. Add responsive candidates only when you actually publish additional files.
