This is what I do...
Save the pic on the hard drive. Then I use Paint (because I don't have PhotoShop, or anything else) to make it fit the dimensions specified by Steve.
Go to Image...check the attributes. Then I use stretch/skew to make it fit.
Not the best way, but it works for me.
When you have the correct dimensions save it again then go to the USER CP and upload then save. Good Luck. :wave:
