;
; Photo Frame script  for GIMP 2.4
; Original author: Alexios Chouchoulas
;
; Tags: decor, frame
;
; Author statement:
;
; This is a rather simple script to produce a photographic frame
; around an image. This resembles a simplistic full-frame print: a
; thin black frame outlines the photograph itself, with thicker white
; borders around frame and picture. The colours and thicknesses are,
; of course, customisable.
;

; Written on top of Chris Gutteridge's (cjg@ecs.soton.ac.uk) Fuzzy
; Border script (which was only used as a template, but there you go).
