I read something very exciting in photographyblog today! It is all about squeezing jpeg file even smaller without loosing detail! Is that possible? ;)
According to the press release:
"Human Monitoring Ltd today announced the global availability of its new hipix™ still image compression technology. hipix™ enables users to send (and store) high resolution images at between 15% and 50% of the size of normal compressed (jpeg) files! hipix™ works on Windows, Linux, Mac and the Android mobile platforms."
