Whats the difference between GD1 and GD2?
GD2 is an updated version of GD1 and, as such, will create pictures with better quality (intermediate and thumbnails). Here’s an example taken from w-nailer: about resizing (Original pic size: 1024 x 768 pixels):GD 1.8.4: ImageCreate ImageCopyResized 128 x 96 pixelsGD 2.0.1: ImageCreateTrueColor ImageCopyResampled 128 x 96 pixelsUpgrades of the GD lib after coppermine has already installed will not affect pictures that were previously created. It will only affect those created after the upgrade. Unless you are running your own webserver, you cannot upgrade nor install GD lib – only your webhost can!

The main difference between GD 1 and GD 2 lies in the color depth: GD1 only supported a limited color depth of 256 colors per image. This lead to very poor quality. By now, the GD1 library is totally outdated and should only be found on very old hardware. If you’re webhosted, you should have GD2. If your webhost is still only offering GD1, it’s probably time to look for another, better webh
