As usual with extensions - no documentation. I have installed it and turned it on. I see no sign of it anywhere. I would have thought it would come up when I click Image while editting page content. Nope. Nothing. Very frustrating. I've been a computer programmer for almost 30 years, Joomla for 3. I think I understand how these things work. Wasted half an hour on this. A word to developers out there - PLEASE WRITE SOME DOCUMENTATION FOR YOUR PRODUCTS!
