The beauty of this is that it's entirely lossless. I've found optipng to be a little better than pngcrush. You can find advpng on Debian/Ubuntu as is part of the advancecomp package. Advancecomp is quite handy, and can work on a number of different file types besides PNG (including plain old ZIP). Some years ago I hacked together a KDE service menu to automate this: http://kde-look.org/content/show.php/Optimise+Compression?content=17552 Also, it can help a lot to index your PNGs and GIFs before you save them. For JPEGs, you can try jpegoptim. I haven't used it so I can't vouch for it. -- "Sadly, a kernel by itself gets you nowhere. To get a working system you need a shell, compilers, a library etc. These are separate parts and may be under a stricter (or even looser) copyright. Most of the tools used with linux are GNU software and are under the GNU copyleft." - Linus Torvalds, 'Notes for linux release 0.01', 1991
