Alt text travels with the image when you publish.

Questions about this tool
What does this check?
Rules of thumb only: that something is written, that it does not start with a filler phrase, that it is not a file name, and that it is a sensible length. It cannot see your image, so it cannot tell you whether the description is right.
Do I need an account?
No. The tool runs in your browser and nothing you type is sent anywhere.
