Logo display template

[Blighty]

I don't think you will find a single template to do all logos. Each logo/background combination will have its own workflow. Not too difficult to do from scratch with the basic Gimp tools. You will need things like: Perspective Tool, Shadows, transparent cutouts, etc. Each of those are quite easy to do. Use lots of layers: one for the logo, one for the background, one for the shadows, etc.
