TableViewdragger is an open source component submitted by Kyohei Ito providing a custom image table view with drag and drop capabilities.
TableViewDragger is inspired by Facebook post editor, and automatically zooms out when the user drags with a long pan gesture, and spaces different images to show where the dragged image would fit.
With TableViewDragger the zoom can be shut off, the speed of the dragging can be adjusted and more.
This animation from the readme shows TableViewDragger in action:
