Any tips on maintaining image quality on vectors... I'm finding that I get different image qualities for different sizes of vector image - like my avatar for example - it seems to pixelate at the tips... I'm saving it as PNG and I've tried GIF as well.The vectors on this site: http://cottonbureau.com/ seem to be really crisp - is there anything I can do to improve the quality generally?Might it have something to do with DPI?

PNG and GIF are web graphics format and will always be pixelated. For Vector images you need to save either AI, PDF, EPS.

This is a 72dpi image exported from illustrator without anti aliasing on.

Same image exported with anti aliasing on.

That might have something to do with it. It does more than double the size though, 3kb right up to 8kb.

It should work fine with default settings to be honest. Can you take me through your process from beginning (blank canvas) to end (uploading the image to the forum) as I'm sure there is something odd going on here!
