The prior version of CNCC automatically creates G-Code from the .jpg and the level of darkness (Doggy) you select; I assume the new version does as well. However, the G-Code is not very efficient, so it's sort of slow.

yes after hours i find it out. always try to upload picture on the wrong window, where is the gcode  button upload button, until find out i have to use the menu above where we can also zoom and invert etc .... :) now its works.have some thing for the brain next days :)
