Image Display Issues on Win XP

[Bill Marriott]

Yes, that is the basic idea... whatever is going to be the least demanding 
on system memory will work best. Use actual thumbnails when possible; load 
images into memory only when needed.

Another method to consider is to keep the images out of the stack; encrypt 
the images on disk (encrypt command); and decrypt them (decrypt command) as 
they are loaded. This will make them slightly larger on disk and use more 
memory, but it will keep your stack small and stable.

Keep in mind that without extreme workarounds (i.e., using certain DirectX 
routines), images are never really secure on a computer; a press of the 
Print Screen button will put that picture on the clipboard. By embedding 
them in a stack or encrypting the image files on disk, you're only making it 
a little less difficult to access them.
