Yep good point galactron22, unless you're rendering directly for use on the web, saving as a .jpg will give you inferior results particularly if you are going to be doing postwork in another program such as photoshop! remember each time you resave a Jpg the quality goes down. so even if you are planning to post your image on the web wait to save as a jpg till after all postwork in Tiff or other non lossy format is done.
