Yeah, my first products went back to P4, you had to include RSR, or whatever they are called, images as well as PNG thumbnails. Lot of other pains as well. Had a customer service problem with a lady using my tongue morphs with two V4's, the poses were crosstalking and she couldn't figure it out. I hit my head against the wall until I remembered Crosstalk was fixed in P7 or P8 and all I had installed was P8 and PP2010. She was using P5. That is about 15 year old tech.
