OP here. Just to flesh out why Monogram is better than your average Instagram gallery, we import all of the images to our db and allow users to create galleries from any of those images.

If you have a cool photo you took a year ago and one from yesterday then you can easily add these to the same portfolio. You can also filter by your most liked and most commented photos.

These are features not available through the Instagram API so we built them and we think it's pretty cool. We also periodically refresh the images to keep their comment/like counts up to date and use the realtime API to pull in new additions.

Any feedback welcome!
