Actually I found it quite difficult to handle. To post the obverse and reverse together as one image, I'll have to combine them and edit them as one. And I'm afraid but I have to say it isn't too user friendly until you get the concept. What is more annoying is the point when you wish to rearrange them. Usually I have my images kept seperately in different folders and labelled the files as obverse and reverse and such. But with this, only the file name is taken, and so there are plenty of confusion with my own naming method. I guess I have to rename my files to fit in with the gallery here.
