Most image formats are already compressed in some way. JPEG, GIF, TIFF, and
PNG are almost always compressed. Compressing an already-compressed data set
doesn't usually buy you very much at all, 1 or 2% if that.

See above. zip will work, though tar combined with bzip2 (or xz/lzma) may be
more space-efficient at the cost of it taking longer to compress and
uncompress the data. That's "tar cjf images.tar.bz2 images/" or "tar cJf
images.tar.xz images/" to create compressed tarballs of everything in the
images/ dir. Replace "tar cjf" with "tar xjf" to uncompress.
