I then modified them with photoshop, (or Gimp if you like). The new images (icons and frames and scripts if you have any) are then registered or listed in the extension text file in the folder you made in FG/ extensions.
This root folder in FG extensions doesn't need to be converted to a .ext file (by zipping it and changing the .zip to .ext) and will show up in the list of extension for the ruleset you defined in the extension text file.
Others here know alot more than I about this, but this should at least get you started.
I may put together a video showing this and explaining how to create the graphics, which is more my area, but I can't say when.
Baz.
