Alt Text field holds up to 2000 characters. Copy from text and post into field is recommended. If the information is on a webiste, include a link in your main message.

I've re-uploaded the image with alt text, the issue is the alt text is longer than a post allows so it literally needs to be in the alt text, not just a post.
