It would be great to have GD take care of resizing images.
1. Quicker to upload one image during data entry and have the script take care of the rest. This is something that only oscommerce carts seem to ignore.
2. Datflow. Imagine uploading a file of 2000 products. Then ftp the images needed into a directory. Run a script and it automatically risizes all 2000 products.
I think there are many people out there that would like to upload just one image and have the script take care of the rest?
