Describe what the collaboration image needs to communicate
A concept gallery may rely on a picture to explain a product relationship. W3C’s informative-image tutorial says a text alternative should convey the visual meaning or content, based on why the image is included. For a collaboration page, begin with that role. The goal is an equivalent useful explanation, not an extra sales line or a keyword list hidden in the image description.
State the image’s job
Look at the surrounding heading and text, then identify what only the image adds. A front-and-back concept might explain two proposed views of one object. A character crop may introduce the selected visual reference. Keep the description tied to what is actually shown and use the confirmed character name where appropriate. Do not add material properties, dimensions or commercial status that the image cannot establish.
Try one concise original description
For an invented example, a useful description might be “Front and back studies of a proposed notebook, with the character image on the front and a small motif on the back.” Use it only when that is the information the page needs and the image truly shows it. If the same explanation is already fully present nearby, reconsider the image’s role rather than automatically repeating the sentence.
Review the page as a sequence of information
Read the heading, surrounding explanation and proposed alternative together. Ask whether the person gets the necessary relationship without a redundant catalogue of colours and edges. Have the actual implementation and assistive-technology behaviour reviewed as appropriate; a well-written draft alone does not prove the whole page accessible. Keep the description with the selected image version so later artwork changes trigger a relevant wording check.
