Eron,
I resize on the X axis only and let the Y fall where it will -- I'm more concerned
about the width than the height on my sites. This retains the aspect ratio and
retains image quality. If you try to force the image into a ratio that differs from
the original, you will have distortion. There is no way to avoid this, as far as I
know, without cropping the image.
If you are concerned about the size, you can check the size when they upload. If the
size exceeds your maximum after resizing one axis, delete it. CFX_DynamicImage
(http://dhinet.com/CFX_DynamicImage/) allows you to get info on an image as well as
resize. Not free, but works well and is well documented.
Hope this was helpful.
