Sorry if I was unclear about the "onmouseover". It's not a preference that you can select in your browser settings. It's a Javascript attribute that a webmaster can add to their coding to, among other things, display text when a user's mouse passes over certain text, images, or other objects.
As for "ALT" tags, those are traditionally used for text-only browsers like Lynx, or for users who turn images off in browsers like IE/Netscape. In place of the images, the ALT text will be displayed for them.
A lot of browsers now (ie. the more recent IE's and Netscape's), will also display ALT text for a user in a little box near the image when they hold their mouse over the image for a second or so. This is what you've been seeing. As far as I know, there's not a browser option to turn this on or off.
