API for Photo Grid to be implemented with ionic

I am looking to create an ionic app which will have a section that shows a grid of photos kind of like instagram :smile:

I want the user to be able to:

  1. create new photo albums on some site
  2. Have the app dynamically add those photo albums to a dropdwon and on drop down select, the app will display the photos for that album in an ionic grid.

Does anyone know of any site, API’s, tools that will allow the user to add the photo albums and then let me to get the JSON from an API?

Thanks!
