I think all of them can deal with compression when they are decoded, but
after they are resized most image libraries allow you to specify a
compression ratio for compressing JPEGs, perhaps not all tags implemented
this feature, so you want to look for a tag that will let you specify a
compression ratio.
The reason the resize creates a larger file, is because most compression
algorithms for JPEG default at 75% where you might have made the file with
50 or 25%
I am currently working on a Resize tag, it will be written in Java, and the
source will be available.

Subject: Image Resizing tags
Hey gang -
Does anyone out there who's messed with tags like "CF_ImageSize" have any
info on the nature of the files these tags produce, especially when it comes
to running pre-compressed images through them? I'm digging around trying to
settle on one of these tags, but I don't want to end up tossing, say, a 3k
JPG through one of these tags, trimming it down width/height-wise, and end
up with a larger file than I started with because the tag couldn't deal with
compression.
Thanks in adavance,
--Scott
