Hello Spin-docta,

I reverted some of your edits to this article as it was unclear what the intent was. You removed several software packages and added the comment "Filesize Optimization is the process compressing images to use the least amount of memory. The trade off for compressing the filesize is that the image loses some of its information.". Firstly it is unclear why you removed these packages, so I restored them. Secondly the comment is not strictly true. In the case of PNGs, and programs such as PNG crush, it attempts different parameters during the lossless compression of the image to optimise the filesize. The only tradeoff is the image compression to CPU time (compress/decompress), as well as the author's time to write the program. I think you may have it mixed up with fourier & quantisation based techniques, such as the JPEG format. User A1 (talk) 16:11, 23 April 2008 (UTC)
