+Foreground Image
+=======
+
+Description
+-----------
+This patch lets you add a foreground image to your lock screen.
+
+Configuration Options
+---------------------
+* `imgpath` - is path to image to display, image must be xpm file
+* `imgwidth` - width of the image
+* `imgheight` - height of the image
+* `imgoffsetx` - image offset from left side
+* `imgoffsety` - image offset from top side
+* `showimgonlyatstart` - if set to 1 image will be shown only at the start (before tipying), if set to 0 image will be always shown
+
+
+Xpm Image
+---------
+Xpm image is bitmap image used by X Windows System. It's one of the few image formats that is supported by Xorg by default.
+
+Convert jpg to xpm:
+```
+convert image.jpg -geometry 1920x1080 -colors 216 image.xpm
+```
+
+Notes
+-----
