As long as I've played this with girl packs, yes it did.

Why it was loading all the images into memory was because when you call open on a fstream object or pass it a file name for the constructor, the file is loaded into memory if it exist so that it can be worked on in memory. Since working with memory is faster than working with the hard drive, it makes since to just load the data into memory if it exist, and work with the data in memory instead of having to constantly read and write data to and from the disk.

Sorry, it is just a pet peeve of mine that sometimes coders don't think about the side effects of what they are writing in terms of the code itself and the preformance of the code.
