Well, was reading the AdaptiveGimp postings and found a plugin -- as referenced by Rod -- which I didn't have: Line border. Cool script. It just happened to have been recently updated also (Monday). I was playing around with it a little just now. Pretty good script with lots of options/variations.

Yes i like it now that i can use it
Thinking about adding some Glade files to Gimp-2.6.11 and see if i can get it to work there.

same here for 2.7.3

I like the line border very much. Lots of excellent options.

I also downloaded lineborder2 and placed it all in plug-ins but it doesn't work.
