It seem that coppermine would alter the original image no matter what setting I change. I can tell this by looking at the image upload file size on coppermine and my original image. They're never the same. The Jpeg quality settings is a configuration that change the quality for both thumbnails and original image. My question is, is there anyway to make coppermine bypass the original image and never touch it in anyway? Thanks for any helpful info.

In coppermine settings under "Pictures and thumbnails settings" you have two settings that you should probably adjust:
Max size for uploaded pictures (KB)
Max width or height for uploaded pictures (pixels)

Yea I've adjust those two things and they don't help. I obviously want to retain my original image as is, so I increase both value to 4000, both are over my image specification, it still modify my original image. Are there any other fix?

Unfortunately that don't do anything either. When I increase quality to 100 the image still is not better than original and the file size increase by 200% minimum sometimes 300%. Why do coppermine feel the need to mess with original image?, or at least have an option to turn it off. Arghhh.

I try on two different image with two different pixels.
Original image:
1600 x 1200 pixels 388 KB
1024 x 768 239 KB
After upload to coppermine with image quality at only 90
1600 x 1200 pixels 522 KB
1024 x 768 269 KB
This is done with settings for width, height and size at 4000 so coppermine wouldn't touch the image but it still change it.
I tried both with GD version 2.x and ImageMagick both modify original image with max settings. You can test this yourself on your coppermine and you will see :).
