Rick...

You're probably off on your testing. Your source image is fairly low quality
to begin with. A good quality photo of that size should be around 100k or
more, this one is only 30k. Look at the area just to the left of her chin
and on her hand...you can see some pixelation. Start with the highest res
image you can find, one that's crystal clear, then work with that one.

Also, you really need to change your compression settings. The difference
between 90 and 95 is going to be barely noticeable to someone who works with
images all the time, much less to these code jockeys.

Try a 70% and a 90% setting along with the higher quality original, then
let's try again.

Can anyone tell me if any of these three thumbnails are of better
quality than the others?

http://www.opensourcecf.com/imagecfc/thumbnail_test/

I'm playing around with some of the java image rendering settings trying
to get better thumbnail quality out of image.cfc, but I have 20/50
vision even when I'm wearing my glasses so I can't be relied on for this
kind of judgement :)

They're actually each slightly different in size, but even if I load the
thumbnails into photoshop and blow them up 300%, I can't tell the
difference.
