Hello Chris,
You're right. The Edge browser don't show the orientation of image and it get js error.
I've fixed this problem in your website, you can update cache and check it.
The temporary solution:
1. open the file: \libs\upload\jquery.fileupload-fp.js
2. find row ~140:
3. and replace it to:Code:Only registered members can view the code.
Code:Only registered members can view the code.
