Ralf,
This is still not self contained. The main problem is you didn't send
1.jpg. You should prefer programmatically generating the input rather
than needing an external file when creating small test cases like
this. Also, the includes are missing, main is missing, etc. The ideal
case (for me, and I'd imagine anyone else trying to help someone) is
to be able to copy+paste+build and see the exact same thing you're
seeing.
David
