What job does the image do?
1. Informative images: describe the useful details in context.
2. Image-only links or buttons: explain the destination or action.
3. Purely decorative images: use an empty alt attribute (alt="").
Keep descriptions natural and review them alongside the page text.
For a product photo, a useful description might be "Navy backpack with a front zip pocket."
