Bind $flow.files[0] to existing $scope.img

[snobrdinrtiste]

I came across a thread (#37) for binding to an existing image but not sure how to implement it... is there an example on how to bind a scope variable (that contains the base64 image) to $Flow.Files[0] ?

Edit: So basically... what i'm trying to do is different from issue #37. I'm trying to incorporate ngcroppie in order to zoom/rotate a selected image and then bind that zoomed/rotated image to $flow

any help would be appreciated
