+===========
+
+Description
+-----------
+This patch allows for the use of images instead of colors
+
+Notes
+-----
+Specify images by replacing the color in `config.h` with the absolute path of the image,
+This can be used in conjunction with normal color values.
+
+This patch is based on the `background-image` patch and depends on `imlib2`
+Like `background-image` it renders each image per monitor so that they are all scaled properly.
