A while ago I experimented with different upload packages for Amazon S3 and thanks to other peoples work everything was working just fine.
Then I discovered cropper and the meteor package jonblum:jquery-cropper and thought I can integrate the two. So I had my demo upload images to S3 and in a later step crop the image to upload a thumbnail of choice.
This solution has stopped working, however, due to the cross origin restrictions between the browser and image store (S3 in my case) somewhere in-between browser updates. I am on latest Chrome, Safari and Firefox and neither browser allows the canvas.toDataUrl method on the image coming from S3.
Does anybody here now how to deal with this or how to solve it?
