Image storage server plus activeadmin

Hi guys,

I want to create a portfolio for a photographer and here how I imagine
it under the hood:

  • Images will be stored on image hosting server (maybe cloudinary, is
    there anything else which is free to test and more or less cheap to pay
    for?)
  • An administrator can load files by logging into active admin
    dashboard, but I do need some process to load images like paperclip.

I am stuck in looking for the easy way to combine all those things. I do
found the Attachinary gem but it is not maintained anymore and I am
afraid that its too buggy.

Any advice from ruby experts?
