Compressing PNG Files

PNGCrusher is a handy utility for those of us who often struggle to keep images lean and mean. I have witnessed first hand a png image of size 2.7 KB getting compressed to 151 bytes! (~95%) by PNGCrusher. Excited? Here's how you can get it and use it:-

To get it, click http://downloads.sourceforge.net/project/pmt/pngcrush-executables/1.7.9/pngcrush-1.7.9-win32.zip

PNGCrusher is a command line executable. So, if you'd like to use it from explorer's context menu, follow these steps:-
1) Extract pngcrush-1.7.9-win32.zip
2) Copy pngcrush.exe to windows\system32 folder or to a folder that is in the system path
3) Open Control Panel and choose Folder Options. Select the File Types tab, and scroll down to the ‘PNG’ entry. Click on ‘Advanced’, then click on ‘New…’.
4) In ‘Action’, type Crush, and in ‘Application used to perform action’, type the following:
pngcrush.exe -e _crushed.png "%1"

That's it. Have fun.
