Image compression results
I get results that I hardly understand about image compression :

http://www.webpagetest.org/result/120713...ess_images

But nor Jpegtran nor ImageMagick does allow better compression of this image:

Original : 50.497 bytes
jpegtran -copy none -optimize : 53.244 bytes
jpegtran -copy none -progressive : 50.497 bytes
convert -strip : 53.273 bytes
convert -strip -interlace Plane : 50.550 bytes

I made the same constation on a lot of others images...

Could somebody tell me what tool could be used to obtain the gain displayed par the result page (about 20Kb !!!) ?

Thanks!
