Im trying to make a sig where it rotates between 3 different sigs. Kindve like my avatar, just with sigs instead. How do I do this?

 

adobe image ready

 

I know that, but how do I do it?We're talking about reputation points too...if u help.....

 

not my tut.. any questions u have after that feel free to PM me and I will be willing to help ualso instead of changing transparency to 0.. I basically just close the eyeball on the other layers.. then hit new layer in the animation tool box... then close all eyeballs cept for the next layer u want to be showing....again.. just PM me if u have questions
