What do you use to save them?

Adobe has a special setting to "Save to web.." and it shows you how many KB you are saving them to. You can reduce them without messing up the quality too much. You can easily save a nice quality signature and still be under the limit.

They did take a bit to load for me and I'm on a cable modem, but seeing as computers are different, they probably load faster/slower for some.


EDIT: Here's a bit of an explanation..
