You can use maps on your GPS with Garmin BaseCamp without having them installed on your computer. However, this doesn't work with every map.
With IMGmod you can modify any map so that it will show up in BaseCamp.
Using IMGmod is simple: put IMGmod on your desktop and drag the .img file with the map onto the icon of IMGmod.
When the .img file is read-only obviously this will not work; so check that first.
Caution! Create a backup of the .img file first
