Dropping a Pin on a picture

Dear raywenderlich community!

I require some help with what I am trying to do. I have done research, however I have been unsuccessful in figuring out how i could do it. The idea is that you want to drop a pin on a picture and on the picture might also be additional pins as well. I have read about annotations and MapKit, but I do require guidance here with this. With the pin also comes coordinates/location and also want that. Is there a different framework that I should use?

(Loving the configuration of this website. :))

Thank you,
