When you're submitting a screen shot, does it have to EXACTLY be the size that it's required to be? Or can it be somewhere around it like 815x600?

^ Do you mean, when you're submitting layouts to Createblog? If so, this should be moved to Createblog support.

If you're talking about Createblog submissions, screenshots need to be in a 4:3 or 16:10 resolution, which 815x600 is not. Some examples of acceptable resolutions are 600x800, 1024x768, 1280x800. If you submit a screenshot that is in an incorrect resolution, an error message will pop up and inform you of the mistake.

If your screen is 815x600 (which I don't think I've ever heard of...strange), just crop out 15 pixels by changing the canvas size.

That was a massive pain in the ass when I had a 16:9 screen.

I thought you weren't allowed to crop your screen shots though.
I thought screen shots had to already be that required size rather than cropped to it.

And I'm referring to submitting Myspace layouts in case I needed to mention

Well, I don't think Createblog will be able to tell if you crop off 15 pixels, just saying. If you're really concerned about the screenshot size, take screenshots on a computer that you know has the right dimensions.

I think it means not larger than.
