For Poser save as jpeg with quality 85-90% For PhotoShop as as jpeg with quality 85-90% For Paint Shop save as a jpeg with quality (15-10%) (the inverse of the other two). For large images >= 800xnnn is useless and waste of file size to compress beyond 10% (PaintShop), others 90%. With thumbs maybe you need to increase the quality, not to much if not you go off the 15K limit.

Stupidity also evolves!
