Dalantech,
I was playing a bit. I know what you mean about graphics files being huge. I was playing with adding graphics into the mod. Here is one I was playing with today. I went with the square corners as even with the graphic corners saved as transparency they where not transparent under my colored backgrounds. One a white background they are fine.
Test Forum I managed to keep every graphic except the top one to 41K. The top one ended up being 1705K with only that one little graphic. Now if I convert to jpg that can save that to 1300K
