If the single and double clicking did not work please right click on the red X, a floating drop down dialog box should appear, click on properties and if a file type is present please record it and post (as we can walk you through fixing this [probably]) but if not Storm is correct that a firewall or other security from a network server is precluding the image file from being viewed on a workstation or that the server will not allow graphic files in excess of a given size to be viewed on a server.
