Maybe you have one of these already, but I don't know where to find it...

How about a sticky (so it doesn't get lost in an old thread that originally started on another subject) on "How to Best Prepare Your Files for Viewing on f295"?

The only hard and fast rule seems to be "Make it less than 100K", but this is still a big file and I've seen Tom ask many many times that people make their files even smaller than that.

I'd love to oblige, but find that compression leads to visible blocks and jaggies in the image. Other people don't seem to have this problem - their files look fine at small sizes, so obviously I'm missing something, but I would really like to learn.
