DO NOT DOWNLOAD THIS APP!!!! I literally just downloaded it for 2 seconds and it began breaking ALL the images on my site. After removing it, a few came back but now, even when I deleted the broken images, and upload new ones, it breaks those too.
I had so much planned for today and this app just added several hours of work for me. Worst download ever. Save yourself the trouble, it's going to cost you time and money. No wonder it's free.
