Instagram has abandoned wording in its new terms-of-service agreement that sparked outcry from users concerned it meant their photos could appear in advertisements.

In a blog post late Thursday, the popular mobile photo-sharing service says it has reverted to language in the advertising section of its terms of service that appeared when it was launched in October 2010.

Instagram is now owned by Facebook Inc. and maintains that it would like to experiment with different forms of advertising to make money.

Its blog post says that it will now ask users’ permission to introduce possible ad products only after they are fully developed.

The outcry to the changes announced earlier this week led the company to clarify that it has no plans to put users’ photos in ads.
