Hi all,

because we all like to post our images in high-quality, i assume, i came a while ago
Google's new Guetzli jpeg Encoder, which helps us all to save a lot of bytes, without
loosing to much, if any, visual quality of an image.

Here's a short test of mine:

bw_final.png = 878.279 Byte (OS X preview)


bw_final2.png = 647.629 Byte (run through pngcrush)


bw_final3.jpg = 188.445 Byte (pngcrushed image run through Guetzli)

Note: Guetzli consumes lot's of memory and takes also time to encode an image, but the results
are imho worthwhile.

Stefan
