The fix? With SafariStand (and other plugins like Saft may provide the same), go to SafariStand Settings » Site Alteration, and enable it for images.google.com. Next, check the Alter box for Javascript and leave Javascript disabled. It should look like this when you're done.
Next time you do a google search, google will automatically redirect you to the javascript-free version, and all is good!
[robg adds: This is a very annoying change; flashy mouseover effects come at the expense of easy usability. You can fix the site in OminWeb using the Page Info section (Command-I), and in Firefox using probably any of many extensions -- I tried QuickJava, which gives you a global Javascript on/off button on the toolbar (just click it before running an image search). Unfortunately, I couldn't find a similar tool for Camino -- if you know of a way to quickly toggle Javascript on and off in Camino, please post in the comments.]
