The following script creates a thumbnail for image/ps/pdf files.  
it can be used with "Execute edit" and "Execute new" configuration commands  
in order to get resized thumbs of attachments.  
  
It uses file(1), convert(1) for images, gs(1) is also required for ps and pdf.  
  
You have to start elogd with the "-x" option to enable execution and put  
something similar to the following in you configuration elog file:  
  
Execute new = /path/to/make_thumbs -s 650 -q 95 $attachments  
Execute edit = /path/to/make_thumbs -s 100 $attachments  
  
make_thumbs have to be executable by the user running elogd, of course.
