I've recently gone through all my old posts making sure the ones that can't have the alt text put as mouse-over text (mainly because if you put your mouse over them, that would get in the way of reading the speech bubbles) have a link to let you see the alt text through Google's wonderful text-only caching. These are seen as a link to the "text-only version" at the top-right of the post.
But why? Why did you do that?
