I have been an exclusive contributor on DreamsTime for almost four years and need to make more money on my portfolio so I am going to try and get on the top 9 microstock sites. Can I use DT model releases on SS, iStock, Fotolia, 123RF and others? I sent this question to SS about a week ago, but have not heard anything back from them. Thanks for the info!

Simple answer- no,  especially iStock. You must use their MR.

I use the iStock release for other sites as well. Easy to modify and haven't had any rejections.

probably yes but its better if you use a generic MR

They all accept releases from the "easy release" APP.

You're getting some bad information unfortunately.

Shutterstock will accept the English version of the Dreamstime release.
