it says that the picture i am using is not a valid picture. How can it not be a valid picture ?? how would i resize it to be able to fit?
download and install
irfanview.
open it up, and open up your picture. click image > resize, and click on the box to save it as a % of the original. put something in there, like 50 or 75, depending on how big the original is, and click ok. then click file > save as, and save it as whatever.jpg, then try to upload it again.
