Image editing option for uploaded files
I get the GF does not allow you to edit an image prior to form submission (so I think). I am wondering if there would be a away, once a user is editing their entry, if one of the entries is a file upload field and that file type is an acceptable image, if we could provide a way of basic image editing like crop, scale, rotate
Try this one I just found. I remembered seeing it based on your question
Maybe there is way to handle this via an exiting plugin that would integrate with GV.
