It's very easy to use, I can easily post my pictures with it as well! They have great customer support too which is helpful when having any questions about how things work in general (or if something isn't working).
The only thing that would make this better are more features like being able to upload videos/audio files etc but other than those few minor issues everything has been perfect so far!! We've just started using them recently however we had no problems at all getting our first posts up within minutes of creating an account - they really do help people out quickly without making their user experience difficult.
