Too complex for a simple task

Seems to be packed with features for all kinds of elaborate things, but I just needed to flip one existing image to another (book front cover to show back cover on hover). I have the images, I don’t need to add any text, borders, buttons, icons. After an hour of trying to get this very simple thing done and failing, I uninstalled. I would recommend it if you want to spend a day working out the thousand settings for each flip, but if you just want something very simple like me, I wouldn’t recommend this plugin.
