Wow, so pretty rude, even if someone is not right. And the person posted above has a point. Its not any of those resolutions actually but just resized image and it can't be "better than original one" simply because of original one has it's native resolution and isn't something - even well-retocuhed - resized.

Glad I helped. By the way, you should consider doing some original work instead of repackaging other people's work.
It's 100 times better to get positive comments on stuff which you designed your self.
