Comment:

 Note that there is another codec called jpeg-ls or jpeg lossless, see
 http://en.wikipedia.org/wiki/Jpeg-ls for an explanation.

 The crash with lowres is fixed (ljpeg does not support lowres), I cannot
 reproduce an endless loop with the first file, but please open a new
 ticket if there still is a problem.
