merge r6616 from branch 2.1 to trunk

bug 1701 fixed: support for PNG file in browser direct upload. If the picture is a PNG file, then the "web size" picture is also a PNG file but the thumbnail is always a JPEG file. git-svn-id: http://piwigo.org/svn/trunk@6617 68402e56-0260-453c-a942-63ccdbb3a9ee
