Stock photo contracts

[Artistichuman]

Hi everyone, I'm starting a new type of niche stock photo company and I was wondering about the licensing contracts. I only have images on istockphoto and I was wonder if people out there know if the contracts between the different agencies are different? If you have any contracts I would really like to take a look at them. You can black out all your info, I don't care about that I just want to see what the licensing contracts are like. Thank you all in advance for your help.
