Can not create photo custom object

Facebook's creation tool can be a little silly. When you type in the word "photo" for the object name, make sure you hit 'tab' or click on the word "Photo" in the drop down from the box that appears. If you don't do that, you'll be creating a custom object type instead of using one of FB's pre-defined ones.

Hope that helps,

Glad you figured out the object settings. It can be confusing. If there was something our documentation that was difficult to follow, let us know. We're in the process of overhauling a bit of the docs, and would love your feedback.

when creating the action and object for the Jomscoial photo upload for an album which layout should I choose: list or gallery.

Where are you seeing those options? I'm actually not familiar with those in the Open Graph creation process, but it changes often enough that I may have missed something. If it's something in JomSocial, let me know where I can find it or a some information about the differences.

Thanks,
Alex
