Hello. I have a program that works fine, except that the documents I end up saving are huge. I am only uploading pictures and they end up to be much more than the combined size of the pictures I am uploading. I know there are some tricks I could be doing with NSImage, but I'm stuck when I read the documentation. If somebody could direct me to the types of methods inside the NSImage documentation that would help me save NSImages in a small way, I would appreciate it very much. Right now I am using the traditional unarchive/archive saving/load implementation by saving a single data object that archives everything else. Thank you.
