I've finished completely creating my second myspace background. But my first one wasn't accepted because that "Screenshot must be 4:3 ratio" sign keeps popping. I kept changing the size and re-submitting but it still didn't work. So I tried a different image for the better size to make my second background. Its size, 401x600, is closer to the required size. But guess what!? That sign still keeps popping up. All of my screenshot sizes have been either arounnd 800x600 or under but my background still isn't being accpted!

My screenshot size is 400x601 and it still doesn't work! What's wrong with it!? Does it exactly have to be 400x600 or what!?

I have no clue how many times I've re-submitted my backgrounds, but I don't what I'm doing wrong!

Your dimensions aren't in the right ratio.

3/4 = 0.75

Some dandy examples:

330/440 = 0.75 [3:4]
400/600 = 0.667 [2:3]
401/600 = 0.668 [some crazy irrational number]
525/700 = 0.75 [3:4]
600/800 = 0.75 [3:4]

I'm not entirely sure how the submission process works, but I imagine it uses the PHP function 'getimagesize()'. If the dimensions aren't a 4:3 or 3:4 (dunno if it needs to be landscape or portrait), then it returns an error. You're trying to upload a funky ratio, and even 400x600 is only a 2:3 ratio.

It's so the thumbnail of the screenshot shows appropriately on all it's different pages. It's not talking about the background of the layout, rather the screenshot or image preview of the layout. When you press PrtScn button, your clipboard will take your entire resolution. If you're using an unsupported resolution, use photoshop, or paint to crop the image to the appropriate ratio.

I always test my sizes like that :P I keep a calculator next the keyboard at all times :-D

What Thomas (tcunningham) said. If you want you, I can take the screenshot for you. Just link me.
