Here are some suggestions from asparagus on ifmud:
For the small postage stamp thumbnails, if they link to the main game page I thin kthe alt text should just be the name of the game. If they link to something else, like the links in the “External Links” section at the top, then I think the alt text should probably be the same as the plain text link, e.g. “Story File (z8)”
[…] when you’re navigating through a large list, even the phrasing order matters. i.e. rapidly moving through 50 graphical links is faster if it says “Game Name Cover” vs. “Cover of Game Name”, for two reasons. One less word, but also “Game Name Cover” gives you the changing info first so if you’re specifically looking for something you can move on immediately after hearing the first syllable.
This was another suggestion about the cover art images in search results. Right now, each cover image is its own link, and then the text of the game name is another, second link to the same place:
So from what I can tell, the usual pattern is: For two links, make the graphic link set to aria-hidden=“true”, or move the image and text into a single link and make the image alt text=“”
Otherwise what happens is when you’re browsing you hear “Cover of foo, graphic link” and then “foo” when you move to the next item which is the plain text link. Ideally you only want to hear one of those, the other is extraneous.
For the image that links to the larger image, I think it should probably say something like
"<image description>. Click for full sized image + copyright info"
And on the page with the copyright info the image should probably just have alt text of the description with nothing extra. It’s presumably a non-link image on that page.
