Rendering with Poser I save with 90%, with PaintShop I use 15 (the inverse 100 - 85%), quality above 90% doesn't make any visual difference, so saving with 100% is a vaste of filesize. The only problem with jpeg is when you have small pictures 200x200 or less like thumbs, here you need to increase the quality to 95-98% for very small sizes and many times gif produce better results.

Stupidity also evolves!
