How can you change the size of your myspace default picture?

Open your picture with microsoft paint on the top tool bar where it says "image" click on "stretch/skew" then where it says horizontal or vertical you make the numbers "50" for vertical and "50" for horizontal [or any number you like] it changes the size and you can make it long.

hmm, im not sure how to do it "professionally"...but what i would do is... upload ur pic, copy/paste it into Microsoft Word (or anything like that), and resize the pic there by clicking on it and dragging the corners of the pic to the size you want. then, save the pic, and when you go to upload it, instead of using the new way to upload pics on myspace, above it, there will be a little link that says something like, "click here", and before the link it will say some other stuff about browsing pics or something. BUT, thats just what i would do. theres prolly a better way of doing it though. XD
