How can i make the picture thats my profile what i want.

Where are you trying to upload the picture onto your profile? Onto the one box for your avvi, or is it some other place?

Then what is the box you are trying to get the picture into?

Is it the first box that says "Personalized Picture" beside it? Or is it the one that says "Signature" beside the box?

Oh, well for that you would just put the picture's url into the box withought the "[img]"''ss on the front and back of the url. ^^
