Added a new "forest" type theme. Here are 3 screenshots. To install the theme, download the forest2.zip
http://greedygammon.com/positions/forest2.zip
uncompress (extract) it and put the folder "forest2" into the location where you installed greedygammon in the pics\fullscreen folder
Here are a couple of reduced size screenshots (don't download them, they are samples, the full size images for 1920*1080 is in the forest.zip file)
You can always add your own images. to the pics\ fullscreen folder.
The preferences options tab will list all the folders and whichever one you select will load all the images in that folder (up to max 15 images)
Or you can simply removes the images from a folder you don't like and put your own images into it. For most users, the location will be
C:\Program Files (x86)\GreedyGammon\pics\fullscreen
