Java is completely different from JavaScript, actually. In fact, the two are hardly related to each other.
The latter is the one that is required for almost all functionality on the web, including the upload system here at ATP. The former isn't required at all.
In most browsers there is a checkbox in the preferences to enable or disable Javascript. Just make sure that's enabled. You don't have to install anything.
I'm curious, Ric: on this computer that can't upload photos: can it give thumbs?
