Our county office users have a mosaic raster of aerial imagery to use as a basemap for the county area. For the most recent aerial imagery data, some of our users have a black and white checkboard pattern showing up when they add the data into ArcMap, as opposed to the photography of the land. We had a similar issue to this before where it was solved by giving the users access to the drive containing the original .tif files. However, that detail does not solve the problem this time for those getting the black and white boxes error. Do you know what else could be adjusted here?
Thanks,

Solved! Go to Solution.
We figured it out. The network drive where the mosaic raster data was stored was not mapped on the machines we were using. Once we mapped the network drive, we created a folder connection to it in ArcMap. After restarting the machine and re-adding the data to ArcMap, the imagery displayed properly.

If you right-click the "Image" in the TOC and select Zoom to Source Resolution, do you see it then?
Often, the checkerboard means there isn't a complete set of overviews made for the mosaic. If you can zoom to the source resolutions and see them (this is making it pull the original .tifs from the source), you will know that the user(s) have permission to see them, and most likely due to missing/incomplete overviews. Though, is a little weird that it is only some users having issues if this is the case.
