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.
