First of all thank you for that great plugin !
I'm having an issue with Jpegtran. Since the last update (2013-3-19), i'm getting this message :
jpegtran: MISSING Copy executable from /homez.577/lesgoute/www/wp-content/plugins/ewww-image-optimizer/jpegtran-linux64 to /homez.577/lesgoute/www/wp-content/ewww/jpegtran or a system path (like /usr/local/bin), OR Download jpegtran source
I've downloaded your http://www.shanebishop.net/uploads/jpegtran-linux64 and put it in the wp-content/ewww/ folder, and name it jpegtran-custom and it didn't work. I've also changed the writing permission and still nothing.

Thank you for your help.
