The display of imagery in GeoCue may be controlled in a couple of different ways. In: i) Layer Properties you may have the Always Load Images unchecked. If so, then you will need to select the images you wish to view, right-click and select load images ii) In Layer Properties you may have the Raster Display Range set on the Zoom tab.In which case images will shut off once you have zoomed in or out too far. Perhaps one of these settings is turned on and that is why some of the imagery doesn't display.
