What was the source of the image? When I loaded your image into photoshop then saved it (with a different filename), CF had no problem manipulating THAT image.

Transparent areas of the image were turned pink after certain transformations. I forgot the exact nature of the problem, but it had to do with alpha channel processing. I found an old thread that I had marked when I was debugging my code. Maybe it will help you.

This one goes red and black. Thanks for looking at this. I don't believe this has to do with transparency - since the source is JPEG and the destination is JPEG and all I'm trying to do is resize. Also, I am nearly a noob at Coldfusion although I have over 7 years experience with PHP so I am by no means new at the web dev game. I appreciate the time you've spent. I'm attaching a zip file with the original (in this new case) and the resultant resized image with the colors messed up. Thanks again! - Tim www

I'll be at the lake most of the weekend so I probably won't have any time to look at this further until Monday or Tuesday (Monday is my first day back to work since July 3!)

Unfortunately, that kind of stuff is WAY beyond my limited comprehension of graphical image formats. Rick Root I'm not certified, but I have been told that I'm certifiable! www
