Post facebook photo with link
===

I have an iOS application which could export pictures to Facebook. At the moment I create App specific album during first posting and post "photos" (actually drawings) to this album. 

There is one huge disadvantage of this method - there is no link to my facebook page at all. So this postings don't make any sense for promotion.

I have only one idea at the moment: create own hosting, upload picture there and post link to it, but that requires webapp with hosting == additional expenses.

Is there any other way to combine picture and link to my Facebook page?

Thanks!
