How to identify images that need an alt-text review
An alt-text check helps locate images whose text alternative may be absent or unsuitable for their role. It starts a content review rather than deciding that every image needs a long description.
Start with the right material.
- What you provide
- current document's images with approved DOM inspection.
- The intended result
- List images with missing versus empty alt attributes; do not assume empty alt is wrong.
How the workflow works.
Inventory the selected images and their available alt attributes. Distinguish a missing attribute from an explicitly empty one, then consider the purpose of each image in the surrounding page.
What to check in the result.
Review informative images, linked images and decorative images in context. Do not generate a factual description of an unseen image solely from its filename or assume every empty alt attribute is an error.
Import the CSV with a consistent delimiter and inspect text identifiers, dates and amounts before using spreadsheet totals. Keep the original file available while checking any automatic type conversion.
Learn from the worked example.
The downloadable CSV example uses these columns: Image, Alt attribute, Observation. Compare a complete record with the source before sorting, combining or importing your own output.
