Be careful with credits. In the case of the BOTF images, you'll have to clearly state that they belong to microprose, and that you are not receiving any compensation of any kind for them. That all you did was gather the images for use.
You did not make them, you do take credit for them. You did collect them out of the botf.res and resized them for SEIV game use.
And thanks for getting them. They will make fine addtions to any image collection.
