Q:

Alt Text on Several Graphics

I'm a completely blind user with a screen reader, and while browsing the website, my attention was attracted by this question As I have experience as a blind user, I wanted to make sure the answers were reasonable.  For the most part, they were, accept for this:

From the desktop, Alt + F4 (opens Shut Down Windows dialogue). (If you're not at the desktop, first do enter image description here + D).
enter image description here
2.
R (Goes to "Restart")
enter image description here
3.
Enter

It's possible to figure out what these unlabelled graphics are from the context, but if they're part of some default selection of graphics provided by superuser, they really do need some alt-text.  How can this get fixed? 

A:

When using the markdown editor, the user is prompted to enter an image caption, which automatically gets converted to alt text. Some users are good at doing this, while others are lazy and don't add alt text. Unfortunately there isn't much the site can do to change this – the alt text required for each image is of course contextual, so it's up to the author to make sure they do it right.
I'll edit this particular post to have alt text on the images, but as a site-wide issue, I can't think of any easy solutions. Do you have any suggestions?
