Don't know about Jake, but I suggest you use Gimp.

Gimp is ideal for creating icon files (as in ico file type) although I am not 
sure that's what you're talking about. If converting an RGB file to b&w is a 
problem, you could try desaturating the image while in RGB and then 
converting it to index mode. It is always better to work on an RGB file and 
then convert it to Index mode when the image is complete.   If the icon image 
is displaying lines when rendered, I suspect the image is distorting due to 
incorrect width and height settings in the conversion code, or the icon image 
has not been created with the correct height and width for the default 
settings of an icon file (ie: 16x16 px or 32x32 px).
