Midgardsormr ~ thanks, it is appreciated. I suppose I will take a look at a 1024x768 image and kinda base my elements on what I think would ever be the largest I would want them for that space. I noticed that most of the 'templates' for GIMP default to 300dpi, but I am not sure what dpi a non-template defaults to, or how to change/check it.

Guess there is nothing to it but to do it!

Best,
The Bane
