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. > I was thinking 'zip' would be good 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. -- Matt G / Dances With Crows The Crow202 Blog: http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
