I just found and tried out a dynamic image resizer called ImageCR. It is SO much better than the CFX_IMAGE_MX tag that is currently installed on the CF servers. Is there any way you can hook this up? The license is $95 per CPU.

Thanks
It is already on all servers 
has been for some times.
Edit: I said all servers, it is actually on wincf and wincf2. Not Win2 or Win6, if you are on one of these send me a PM.
Your lucky day! 
I updated my post above, as I noticed a made a mistake in saying all, win2 and win6 do not have this.
