Basically all I've done in the past is in the regular paint app on PC, load the art slide (A_PlaneSide or J_PlaneSide) for whichever side your looking atthen find the plane your hunting for by using the bitmap number from the editor, then just crop that individual plane out, copy it, then load your modded art slide and paste it and line it up in a slot on the slide that you're not using. after you put it into a slot, just count which slot number you use and put that number into the editor under the bit map for that plane. It sounds hard, but it's mainly just crop, copy, paste, in paint app, just make a back up of your original art slide/file, then just play around with it in paint moving planes to different slots and what not. Hope this helps and have fun adding plane art to your mod!
P.S. which art slide are you using? base game? alternatewars.com art? which one? I can maybe put one together for you if you need. I use the alternatewars.com A_PlaneSide art for my starting point.
