 <imgkey>imgname # alpha</>:

 This command will paint an image at the current position with the current scaling. The value of ''alpha'' may run from 0.0 to 1.0 where 1.0 means completely opaque while 0.0 means completely translucent. ''imgname'' is the name of a key in the ini file specifiying the image file to be used. The path is a relative one as known from the 'Image' key. Note that the spelling of the key is important and references to keys belonging to other icons are not possible.
 
+----
+
+In this example slight changes are made to the paint commands. The alpha value was reduced and the scaling factors increased.

+This icon is the result.
