Also, I suspect that JPEGImage is nil. I'm guessing that the line in
ssetImage that reads:
[JPEGImage initWithContentsOfFile:imageFileImage];
should actually be:
JPEGImage = [[NSImage alloc] initWithContentsOfFile:imageFileImage];
(While we're here, JPEGImage sounds like a class - the instance
variable would usually be called jpegImage)
