Apache/PHP Image Compression

RE: Apache/PHP Image Compression
We use a two step process.
1. We use http://www.imagemagick.org/script/index.php with 85% compression rate.
2. we apply a lossless compressioin that strip all meta data using jpegtran.exe
In jpegtran, use the -copy none -optimized for images < 10k and -copy none -progressive on image > 10k

If you don't mind doing a little manual work, you can use http://www.jpegmini.com. It does a really good job compressing jpg and then running #2 on top.

If you want to optimize even further, than you can use webP compression for images. It's native for chrome users, but people using IE of FF will have to install the "codec". All the info can be found here: http://code.google.com/speed/webp/

Hope this helps
