Dear Alex,

Warm thanks for the script.

Alex button works perfectly for documents I wrote, but only partly for a 
pupils thesis. I have so far not be able to find a sytematic difference 
between pictures where it works and where doesn't.

imagemagic: tried it earlier but not in the way you suggest. I will need 
time for this.

One problem, and this might not be so different elsewhere, is that 
collaborators who use Texmacs like me tend to limit themselves to the 
GUI, while those who use Latex anyhow sniff at Texmacs and tell me "I 
told you so, learn Latex"...



Dear Joris,

Many thanks for the offer. I will see if I manage to upload a thesis in 
Texmacs to a FTP server, I think that might be the only way to get you 
something typical with many figures. Again, it will take time, I have no 
experince with that.

I will recontact you.

Best regards,

Werner
