You can't add any abilities to StellarAbilityTypes.txt that do not effect the attributes of the planet itself. Cargo works, resource modifiers and SY abilities do not.

Just point people to download the Image Mod. Including images from it in your mod download is contrary to the main purpose of the Image Mod, which is to only need to download images once for use in many mods. You could even submit images to it and not need to include any in the mod download at all. This also prevents overlaps in the event of Image Msf updates.
