Compress all the PNG files in your Home directory
Authored by: arcticmac on Nov 23, '11 08:18:03AM

While this is true, you usually only save 5-20% on most images, and it's fairly CPU/time intensive. Unless you have a lot of PNG images and _really_ need the disk space, using optipng or pngcrush or any of the others probably isnn't worth the time.

Now, on the other hand, if you're a developer or a web designer and you're generating PNG images that will be distributed (hopefully) hundreds or thousands of times, then PNG optimization is absolutely for you. Just replace the "~" in the original poster's command with the path to one of your development directories.
