the problem is, that you are not using GD-Libary 2.0.36 (or later) and your image isn't using "color RGBA", but "gray+alpha". You can tell this problem by the vertical lines you get.

GD had a problem handling grayscale images with alpha channel correctly, wich was fixed with GD 2.0.36 in the Year 2007.

The solution is to update the GD-Libary to 2.0.36 (or later) or replace every file which uses "gray+alpha" with an version using "color RGBA".

I would advise to update the GD-Libary, cause there is also a serious security problem, that was fixed in the Year 2009 by Debian.

I am really shocked by this, since you are now the sixth person with this kind of problem and this fix is 4 years old and since 2 years known als high security fix by debian.

Best regards
