The other problem with this is that you need to know the original dimensions of the image programatically to determine your aspect ratio. To do this manually for one or two images is fine, but when you have a folder with thousands of images that are displayed dynamically, then this becomes extremely time consuming and inefficient.
Is there some way to determine the original dimensions programatically? I've yet to come across anything that is useful to me - CFX_Image is not an option because I do not control the server in question and cannot install DLLs. Perhaps there's something simpler I've missed?

The only problem with this is you are still downloading the entire image rather than the smaller thumbnail or whatever. I think the purpose is to reduce the physical size/resolution for a smaller download. I've been fiddling with the Perl Image Magick modules for this. Running the commands from cfexecute. It's slow since I don't know Perl all that well....
