Hi Ken, this is indeed the place where I will be able to help you :)
Are the example images are not working? Or is it a specific image? If you can post your logfile I should be able to see what is happening.
Start up PixelCNC and in the Config menu enable "Log: Debug Info". Then load an image that causes the problem. You should then be able to find your logfiles folder from the File menu. You will see text files that are named with the year, month, day, - hour, minute, second, and should be able to find the newest logfile in there just by sorting them by name. Open up the log file and copy/paste its contents into a post here. (In notepad you should be able to press CTRL-A to select all, then CTRL-C to 'copy', then in the comment textbox here paste using CTRL-V).
