ho uses potd to promote?
 

potd=pic of the day..

who uses this to send traffic to sponsors? how effective is it for you?

I used it as a filler on TGP. The conversions generally suck balls. So you need to have a good landing page for the potd.

i do, but i like sponsors with a thumb that changes everyday as well so you can simply add thumbs on a page and have them change out daily.
