Posting Photo to facebook fan page via iOS app by regular non-admin users
Is it possible to programmatically upload a photo to a Facebook page (community one) using Facebook Graph API? (Being not an administrator of this page) If yes, what HTTP request shall be made?
P.S.
Having administrator rights, I can retrieve the access_token of the page and upload a photo (which will be marked as if page itself has uploaded this photo, not an actual user, since we’re using the page’s access_token);
Without administrator rights I can’t retrieve the page’s access_token; if I use the user’s access_token, then the photo is being uploaded to their wall, even though it was marked PAGE_ID/photos, but not me/photos in the request.
No, it is not possible to do this if you are not an admin of the Page in question. If you want to request this as a feature, you should file a Bug report about it.
