I would like to show all people which use my app. I tried this facepile code but it shows my friends only.
<iframe id="fbusage" scrolling="no" allowTransparency="true" src="https://www.facebook.com/plugins/facepile.php?app_id=123&amp;width=750&amp;max_rows=1" style="border:none; overflow:hidden; width:750px; height: 60px;" frameborder="0"></iframe>
How can I show all people using my app in iframe?
Well, there might be a reason for this plugin only showing friends, and that reason might be called privacy …?
If you don’t care and want to do it anyway – in that case, please have a thorough look trough the platform policies first, if that’s even allowed – you can generate such a list yourself. Just read out the stored user ids from your app’s database or whatever, select some of them by whatever means you think are best, and then put out some HTML code that displays their name and picture. (Picture can be displayed via graph.facebook.com/userid/picture, and if you don’t have user names already stored in your database, you’ll have to make a request to the Graph API with the ids first.)
