copying Images with posts using Elegant Themes Nimble

When I copy individual posts and select the option to copy the images, the images display in the target pages but they donut appear in my media folder, even though the urls look correct for the target site? example on page http://ecoshowcase.compago.co.uk/2014/05/21/new-attack-biomass-boilers-cater-larger-heatloads/, the image http://ecoshowcase.compago.co.uk/wp-content/uploads/sites/6/2014/06/NEW-ATTACK-BIOMASS-BOILERSCATER-FOR-LARGER-HEATLOADS2.jpg does not show in my media library?
