Comment (by annakrat):

 So, after some digging around, it seems to stop working since Pillow
 version 3.4.0 and I haven't found anywhere a working version of
 images2gif.py and I haven't been able to find the problem. But since 3.4.0
 Pillow itself allows to write GIFs, so I added it there. Now depending on
 your PIL/Pillow and Pillow version, either the old or the native Pillow
 way is used. The problem is the GIF created by Pillow looks worse, but I
 don't know what could be done here.
 Also we could use imagemagick as a backend if it's installed and
 available.
 Anyway, please test.
