The alt-text thing is cute (here and with XKCD). If the graphic is just a carrier for that, fine; if the graphic is supposed to have independent meaning, then I suspect anything small enough to not be cluttered will be too small to see clearly.
"Don't care" doesn't quite capture this; I think the added info is nice but I'm not sure about how to implement it. Now that I know this is what you're doing I'll hover to get as much of the text as Firefox will give me; I probably won't bother to scroll through the longer ones via properties. (I don't care enough to try to search for the right extension, but if someone provides a link I'll install it.)
