Attached is the ship art Photoshop template I use in a .zip file. It's an 'all-in-one' in the sense that I use it to create both the 'ship side' and 'ship shil' art. I turned on 'maximum compatibility' mode when I saved the file, but I haven't tried opening it in anything other than Photoshop, so YMMV.
I create the ship sides/shils by inserting the ship artwork itself on one layer and then adding the background art on a layer behind that. If the background art layer is turned off, what appears is the 'shil pink' background.
By turning various layers on/off, the ship artwork can be checked for errant pixels which will cause pink artifacts to appear in the game. Depending upon what colors are prevalent in the ship artwork will determine what background colors should be used to check against; in general, you want colors which are high-contrast to the ship artwork colors.
Here's what the layer structure looks like:
Of course, save in 24-bit (8-bit per chroma channel) .bmp format. Any questions, let me know.
EDIT: re-uploaded .zip file with both PS and .tif files included.
