The most useful pictures on a developer project website are the ones that help a visitor understand what you built. Start with a clear screenshot of the finished interface, then add a focused interaction, diagram, or before-and-after only when it answers a different question. Use decorative photos sparingly, and make sure every image is either accessible, appropriately licensed, and prepared for the space where it appears.
Choose pictures that explain the project
A project page should make it easier to assess the work, not simply look more decorated. Before adding an image, decide what a visitor should learn from it: what the product does, how an important interaction works, how its parts fit together, or what changed during development. If a picture does not answer a useful question or contribute meaningfully to the project’s identity, leave it out.
For many projects, a strong starting set is a clean view of the main interface and one or two supporting visuals that reveal something the main view cannot. This is a practical editorial approach, not a universal portfolio formula: the right selection depends on the project and what needs explaining.
- Show evidence: Use an actual interface, interaction, system diagram, or comparison to demonstrate the work.
- Separate evidence from decoration: An illustration or photograph can establish atmosphere, but it should not be mistaken for proof of a feature.
- Choose with a purpose: Each additional image should contribute information, context, or identity that the surrounding page does not already provide.
Picture ideas for developer projects
A clean screenshot of the finished interface
Choose the screen or state that best communicates the project’s main value. A screenshot of a dashboard might show the key workflow and a representative data state; a developer tool might show its output alongside the controls that produced it. Crop away unrelated browser chrome and incidental material where doing so makes the product easier to evaluate. Keep small interface text legible, and avoid a view so busy that the important feature gets lost.

Do not make an image carry essential information that the page never explains. A screenshot can illustrate a result, but the surrounding text should still say what the feature does and why the shown state matters.
A short sequence showing an interaction
A single polished screen can hide how a feature behaves. For an interaction that is central to the project, show two or three purposeful states—for example, a form before submission, a validation response, and the completed result. A small sequence or annotated flow is often clearer than a long strip of tiny screenshots.
Keep annotations brief and make sure important explanatory text also appears as ordinary page text, rather than only inside the image. That helps visitors who cannot see the visual and keeps the explanation searchable and selectable.
A system or data-flow diagram
Use a diagram when architecture, integrations, or the movement of data are part of what makes the project interesting. Label the important components and show the relationships that matter to the reader. A diagram should clarify the system, not reproduce every implementation detail; put a fuller explanation nearby when the diagram contains complex information.

A before-and-after pair
For a redesign, optimization, or behavior change, a matched before-and-after can make the difference visible. Use comparable states and explain in text what changed. Do not rely on color alone to communicate the improvement; describe the change in ordinary language so the point remains clear without the images.
A focused detail or mobile view
Show a particular control, responsive layout, or mobile interaction when it is relevant to the project’s evaluation. A mobile screenshot is useful when the mobile experience is materially different or especially important, not simply because every project page is expected to have one. For responsive delivery on the page itself, provide suitable image alternatives so the browser can select an asset appropriate to the rendered size and device.
A project-specific illustration or photograph
An illustration or photograph can support a project’s identity or subject matter. Use one when it adds genuine context or atmosphere; avoid generic stock imagery that could sit unchanged on almost any developer portfolio. Treat found images as rights-managed until you have confirmed the applicable permission or license conditions.
Compare candidate images before publishing
Apply the same four questions to screenshots, diagrams, illustrations, and photographs. No one image format is right for every project.

| Rights | Do I own the asset, have permission to use it, or understand and satisfy its exact license conditions? |
| Accessibility | Does it need concise contextual alt text, an empty alt value, a visible caption, or a longer nearby explanation? |

Write useful alt text and captions
Alt text is a text alternative for meaningful image content. Write it to convey what a reader needs to understand from the image in its context—not to repeat a filename, add a generic label such as “image,” or promote the project. Read the alt text alongside the preceding copy: it should make sense without needlessly duplicating that copy.
- Informative image: Describe the relevant content or result. For a screenshot, that might be the visible state or feature the page is explaining.
- Decorative or redundant image: Use an empty
alt=""when the image adds no information beyond nearby text and should be skipped by assistive technology. - Image link or control: Describe the action or destination, rather than only how the image looks.
- Complex image: Keep alt text concise and put the important explanation in nearby text rather than trying to fit the entire diagram into a short attribute.
Use a visible caption when it helps visitors interpret or identify an image. A caption and alt text have different purposes: a caption is displayed on the page, while alt text supplies a text alternative. Do not use the title attribute as a substitute for alt.
Rank #3
Search visibility is not a reason to stuff keywords into alt text. Useful alternatives can help search systems understand an image alongside page content, while keyword stuffing creates a poor experience and may be treated as spam. Write for the person who needs the alternative.
Check image rights before using found assets
Confirm that you own an image, have permission to use it, or can comply with the exact license that applies. Conditions may include credit, a link to the source, notices about changes, share-alike requirements, or restrictions on commercial reuse. Save evidence of the source and license so you can verify the terms later.
Search filters on image repositories help locate candidates; they do not replace checking the terms for the particular asset you plan to publish. MDN names Flickr, Shutterstock, and Pixabay as examples of repositories with permissively licensed media searches, and Picryl and The Noun Project as services focused on permissive media. That description is not a blanket license for every item on those services.
Unsplash’s API guidance is specific: “When displaying a photo from Unsplash, your application must attribute Unsplash, the Unsplash photographer, and contain a link back to their Unsplash profile.” This statement concerns use of the Unsplash API; it should not be generalized to ordinary use under the Unsplash License. Check the terms that apply to your actual source and method of use.
Prepare images for the page layout
For HTML images, include intrinsic width and height where appropriate so the browser can reserve space in the layout. When you have multiple image sizes, use srcset and sizes to give the browser information for choosing a candidate suited to the rendered size and device.

Review the image at the size visitors will actually see. A full-resolution screenshot can contain useful detail but may become unreadable when squeezed into a narrow column; a tiny asset can look poor when expanded. Select and crop with the display context in mind, and retain enough detail for the image’s purpose.

If you are capturing your own live project, first prepare a representative state: use realistic content, dismiss incidental dialogs, and make sure the feature you want to show is visible. Capture the relevant viewport or page, then inspect the result for overlays, failed loads, private information, and text that is too small. For a browser-based workflow, use your browser’s screenshot feature or a screenshot tool, then crop the result to the content that supports your point. Do not publish sensitive user or account data from a real session.

Choose the right number and mix of visuals
There is no established universal count of images that makes a developer project page effective. Let the project’s explanation determine the set: include enough visuals to show the key evidence and no more than you can make useful and readable. A straightforward interface may need only a clear screenshot; a project whose value lies in a complex interaction or architecture may benefit from additional views.
Before publishing, check that each image has a distinct job, the text explains information that cannot be inferred from pixels alone, alt treatment matches the image’s purpose, usage rights are clear, and the delivered asset fits its layout. Those checks improve the page without pretending that one portfolio formula works for every project.
Frequently Asked Questions
How many screenshots should I include for each developer project?
There is no universal evidence-based count. Include the views needed to explain the project’s important states or behavior, and omit images that add no distinct information.
Should I use stock photos on a developer portfolio?
Use a photo when it genuinely supports the project’s subject or identity. For demonstrating what software does, an authentic interface screenshot, interaction, or diagram is usually more directly informative.
