“A person at a laptop with floating icons” describes a topic category, not an article. It tells a reader little about what the post will solve. A useful featured image can be modest: a clearly cropped interface, two labeled states, or a simple diagram of the choice the article explains.
Choose the image type from the article
For a tutorial about a software control, use a real screenshot if the interface is the point. For a comparison, a labeled pair of genuine examples may be more useful than an abstract illustration. For an opinion piece, a custom illustration can set the tone, but it should still refer to the argument. AI imagery is a possible ingredient, not the required output.
Before opening an image tool, write one sentence: “The reader should recognize [specific idea] from this image.” If the sentence is just the article’s broad keyword, the concept needs another pass.
Build a brief that leaves room for the title
A practical brief names the subject, what it is doing, the publication format, and what must remain empty. For example, for an article about checking upscaled interface graphics: “A close view of two versions of the same small UI label, one crisp and one distorted; neutral background; room on the left for a short headline; no invented product logo or fake software window.” Use the article’s real screenshots for the final comparison. The generated draft can suggest a layout, but it cannot serve as the test result.
Give the image the site’s colors and a consistent margin. Keep text out of the generated image if you can add it later as editable type. That makes spelling, crop, and contrast easier to correct.
Check the places WordPress will show it
A WordPress featured image may appear above the article, in an archive card, or elsewhere depending on the theme. Preview the real post and its card. A central subject can disappear when the card uses a different crop. Place essential details inside a safe area and avoid tiny labels that only work at full size.
- Thumbnail: Can a reader identify the topic without reading small text?
- Article view: Does the image add context beyond repeating the heading?
- Mobile crop: Are the subject and any labels intact?
- Evidence: Are screenshots and before-and-after states genuine and accurately described?
- Rights: Can every photo, generated element, and stock asset be used for this publication?
Write the alternative text for the image’s job
Do not stuff the post title into the alt field automatically. Describe information the image conveys, or leave the alt text empty when the image is purely decorative and the nearby text supplies the same information. The W3C images tutorial explains how the image’s purpose changes the right text alternative. A comparison graphic with meaningful differences needs those differences conveyed in text; a background flourish does not need a keyword list.
A distinctive featured image earns its place by clarifying the article. It need not look elaborate. If a real, well-cropped example tells the story more accurately than a generated scene, use the example.
