You have to fine-tooth-comb all text within, say, half a mile of the image tag to figure out why on earth the search engine thinks your page about leaf-cutter ants has something to do with teddy bears. And bend over backward to devise a boring-but-accurate alt for each of those images.
Frankly most of the time I just look at the numbers, say wtf and ignore it. Though it is exasperating when you constrain your gwt results to "web" and it still shows jpgs among the results. You're left wondering what it is about your utterly unrelated image that made g### think it's closer to the search term than several million other people's full pages. Or possibly even one of your own pages-- but not the one the image lives on. (And what is the point of setting up a separate Image search if you're still going to throw images at people in the regular search? But that's another thread.)
