You're very right! I didn't want to give people really specific information off the bat because I wanted to get the people participating talking to one another. He's also specifically right about how javascript lends itself to memory. It's just a simple image swap also commonly known as a roll-over if you want to look it up.
Personally, I love javascript, a lot of people think I'm crazy because it's a little inconsistant across browsers. But it gets better and better with every release and it's absolutely free and really easy to get started because everything is pre-configured and installed.
It's very similar to C and C++ (and therefor Java) in syntax and graphics are a snap if you know a little bit of HTML and a little bit about the Document Object Model (DOM). I feel this is because graphics are handled somewhat differently as they're a more integral part of web pages than console applications (generally). So if you want to try it out, there's a bunch of keywords in here all of which can be checked out in depth here:

Or more specific questions can and should be posed on this and other codenewbie forums.
Thanks for the post MrMark.
