Thanks for the input rgthane. We're certainly considering more advanced editing options. However, there are a few legalities involved with CC licenses that we need to wade through first.
Ultimately the responsibility for proper use of the images lies on the actual users of the image, but we want to make sure any CC images we allow to be cropped with Wylio actually allow for that kind of image manipulation in their license.
Again, thanks for the feedback! It is much appreciated.
