Theoretically you should be able to by merely choosing "from computer" instead of "from url" on that drop down image icon menu...and then browsing the hd for the file. But for some reason whenever I try that, it gets rejected as being XKbs above limit. Case in point, I just tried a `17kb avi and it was rejected as being 91.3kb above limit. Figure that one out
So it's possible I'm doing this wrong myself, or it could be a glitch in the system. Hopefully one of our gurus like a wild guy named Bill might wanna weigh in.
