Does exactly what it says

I want to update my review. I have created a site where each of 24 pages has images in left and right sidebars, with each page having a different set of images.

Creating what I wanted would have been pretty much impossible without this plugin, but I succeeded quite easily.

Yes, it is a little complex and there are some tweaks I would add to make repetitive work easier, but the plugin is an exceptional piece of work (from someone who has a plugin).
