epetition software

we are looking for epetition software to replace:
http://www.icanw.org/user/list

as it is buggy on some M$ setups

i have found:

http://www.ipetitions.com
http://www.petitionspot.com/
http://www.thepetitionsite.com/
http://www.petitions.org/
http://www.chimicon.com/petition/

but i am looking for something that can integrate with in our site (run from our server)and is more sophisticated than chimcon.

Ideally we have photos as an option. Open source prefered but am open minded
