There are 5,153,960,755,200 (640*480*(2^24)) true colour 640x480 images.

The file size of each image would be 921,654 (54 + 640*480*3) bytes.

The disk space used by each image (on NTFS) would be 925,696 (ceil(921,654/4,096)*4,096) bytes (plus space used by the directory).

The disk space used by all images (on NTFS) would be 4,771,000,855,245,619,200 (925,696 * 5,153,960,755,200) bytes (slightly under 5 billion Gigabytes).

 

What if you generated 128x128 images using 16 colours?

Num images            = 160,000
File size             = 8,310 bytes
Disk space per images = 12,288 bytes
Total disk space      = 1,966,080,000 bytes =~ 2GB

That's attainable, but it's only thumbnail size.
