This block can display one of the following:

- Your own photo stream (uploads)
- Another users stream 
- All photos with a specific hashtag
- All pictures you have liked
- Your feed (what you would see if you were logged into instagram - a mix of other users' photos) 
- The current popular images 
- All pictures taken at a location (you will need to know the locations id) 

When adding the block to a page the edit dialog will display instructions to simplify setup of your instagram account to work with the block (a requirement added by facebook, but we've simplified it for you) 

The block can display images in a number of fixed sizes with various interface elements or optionally, no interface elements. Images can also be set clickable to launch a lightbox showing  larger version of the selected image.

Please see screenshots for an example of the options you can change.
