I use GIMP software to create CNC carving patterns. And there are a lot of you who would like to know how to do it. So I've decided to create some youtube videos for you.
GIMP is a free, open source software that can be downloaded from the official gimp.org web site found here.
These youtube videos are high resolution. You can change to high res using the gear icon in the lower right corner of the video. You will also find the full screen button on the lower right.

Here is a link to several gimp scripts and plug-ins that were made for me by some very talented script writers.
Download the Zip file here. You can usually right click this downloaded file and should choose to extract it. There's a readme file included explaining where to put the files. When installed these files will give you an extra pull down menu within gimp called [Height Tools].
