How do I plot GALEX detections over an image from another survey?

The fastest way to do this is to use ds9, the image display program freely available from http://chandra-ed.harvard.edu/install.html . Open the image of interest in ds9 (the image must have a J2000 WCS), then go to Region (on main menu), Load Regions, and find the ttttttt_vvvv[f,n]dcat.ds9reg file. GALEX detection ellipses determined by the object size and position angle will be displayed as green ellipses.
