I have tried to upload an image via URL (we keep all of our images on Amazon-S3).
Here's a URL for one of the images that I'm trying to upload: https://s3.eu-west-2.amazonaws.com/davieswallpapers/ACC4DR1.jpg
When I upload the image and click save I get the error 'Error File could not be uploaded' in red.
I have tried to upload random images that I've found on google to see if they would work and they have been fine. I then created a different Amazon Web Services account to see if it was my current account that was the issue but that didn't work.
Any suggestions are welcome.
