I think i am only left with two options by the looks of it, either create my own encrypted data file to go along with the exe file, or to create a header and data section and tag the data to the end.. I have actually done it before but not with tagging image data to the end , but it sounds like dirty programming somehow, but then i suppose its been working for me on a program i wrote 2 years ago....
