Brief flash of the image going back to where it was originally and then swapping when dragging images

[gkimpson]

When an image is swapped, there’s a very brief flash of the image going back to where it was originally and then swapping (with the correct image) - it isn't a massive problem but it causes a weird flicker effect in which the wrong image is shown for a split second. Any ideas why this would be happening - using Angular 1.3.x with the latest version of the angular sortable view library
