Swapping pictures and video clips

I need help guys. I need to be able to swap pictures and video clips which have been added for the wrong actresses for a film called Sexual Exploration. The pictures and video clips for AnnMarie in the movie are of Kirsten Price and the ones for Kirsten Price are of AnnMarie so the ones for AnnMarie need to be moved into AnnMarie and the Kirsten Price ones into Kirsten Price. I do not see anywhere on the edit page which allows you to move pictures and video clips into another actress content. If anyone knows then that would be great thanks.
