External map graphics

I'm doing a Song of Ice and and Fire, so there are lot of good maps already available I might want to use the graphics of.  Is there any way I can use them in this application?

You can drop onto the map or upload ,jpgs, .pngs, and .gifs into your art library.  If you want to get a PDF image into the game there are two primary ways. 1) While in the PDF right click and select 'Select Tool'. Then right click on the image and select copy. Finally, open up an image program (such as MS Paint) and paste the image and save it. Now it can be dropped into the game. 2) If the PDF is less than 5MB in size you can drop the PDF onto the map and it will give you an option to select which page it will convert to an image. - Gauss
