Require alt text for images

I have a blueprint for a page that has 1 image. I’d like to require the user to enter alt text for the image (or at least show a warning if no alt text has been added.)

Is this possible?

Frankly, I can’t even figure out how to add alt text to an image to begin with, so any help with that too would be appreciated.

First you’ll want to add an alt field to your file blueprint. There’s a simple example with such a field in the docs.

For the warning you can use the info of files fields/sections: Accessibility no-brainers · Medienbäcker Thomas Günther
