The practical starting point
A photograph used as decoration and an image carrying important information play different roles. Decide what the reader would miss if the image were unavailable. On a product example page, the useful information may be the feature being discussed rather than every visible object in the photograph.
A workable next step
Review the surrounding caption and text before writing an alternative. Avoid repeating a long paragraph already available beside the image. Do not present a generated scene as a photograph of a real customer or completed job. Use W3C guidance to choose the appropriate treatment, then check the actual page with its image information included.
Keep in your notes
- Decide the image’s purpose.
- Consider surrounding text.
- Label fictional illustration truthfully.
