In the example, I’ve chosen to use OptiPng, but as you will see you can very easily swap it out for a different tool if you desire. Stoyan Stefanov has already done an excellent job outlining how to install each of these optimization tools, so I will simply refer you to his article for installation instructions.

In my experience, pngslim optimizes the best, nearly all the time, but it's horribly slow. ScriptPNG comes very close to pngslim's compression, but it's MUCH faster. The latest version of ScriptPNG was released 2010-03-24. Two advantages that ScriptPNG has over pngslim are: 1) it can convert other image file types (bmp, gif, tga, pcs, tif, etc.) to png 2) it lets you choose from a) fast lossless optimization b) complete lossless optimization c) conversion to paletted PNG without diffusion d) convert to paletted PNG with Floyd-Steinberg diffusion (using pngnq). One LARGE disadvantage to ScriptPNG is that the files must reside in the same folder as the script, so you can't just highlight multiple files and drag and drop them onto the script. I've been thinking of splitting up the ScriptPNG into 4 scripts (one for each current option) and incorporating drag-n-drop, a la pngslim. Usually, I don't have a pressing time constraint, so I am OK with letting pngslim work in the background on the file(s) I drop onto it. However, it would be nice to get ScriptPNG working in the same manner. @Vincent: PngOptimizerCL (the command line version of PngOptimizer) is included with pngslim.

Yes, I am only about 1-2 steps above "idiot" status when it comes to the programming side of the house.
