I don’t know if this service is popular, but I have somehow missed it and I really need it. Instagrid.me is a service which allows one to have all his Instagram.me photos to be in a single place in a gallery format. This is really handy when you want to show someone all of your instagram pictures or want to find an image you did some time ago. Instagram has it’s own feed, but in order to see the images one need to be logged in.
My Instagrid is now available here
