And further, the size of a compressed graphic file on disk is a different beast the
the amount of memory the expanded version takes up. I just created an 8000x8000 GIF
stored with an 8-bit 256 shades-of-gray color table. The raw data for the uncompressed
image is 61MB, but the file size on disk is 47k. (The difference would be even greater
with a 8000x8000 24-bit color JPG, whose uncompressed size is 183MB but whose file
size should be very tiny, but Photoshop couldn't save the file out with the paltry
memory this laptop has, so I can't provide those numbers.)
It would be naive to think that because the file is only 47k that a program should
easily be able to show it in its entirety.
