my images seem to all be layering on top of one another?

Hey guys, I'm trying to make a list of images but they all seem to either be not displaying or layering on top of one another. An example of what i'm talking about can be found here:

you only see one image but there should be two next to one another. The css for the page is here:

http://tech-area.com/files/tabs.css

What i hope to happen is the two images will show side by side as they should, and then when one gets clicked on, it changes to a new image (see the .css file)... I can't seem to make this work.

nevermind, got it! but now some weird thing happens when i try to use this in firefox?
