Dynamically extracting a thumbnail from an interlaced image.
I was wondering if it would be possible to use an interlaced image as the source for both the thumbnail and the full-size image. That way you wouldn't have to keep more than one file for each picture in your photo gallery. Interlaced images give you a lo-res preview while they load, so could you just take that first preview and make it smaller?
If this is possible, does anyone know of a program that does this?
