The Illustrator Plugin is a separate program which is installed at the same time as Kentucky. It gives the illustrator the tool to create all other image formats which is specified for the current image template.
Checkout the image from Kentucky. The default image program opens the file, in this case the Adobe Illustrator program.
After editing and saving the image, the user on the File menu clicks first Scripts and then "Kentucky Production" and "Kentucky ACME" (replace ACME with the name of your implementation) plus "ToKentucky".
Below window comes up. Click "Ok" and wait for the program to generate all image formats. When done it will close itself and you can check in the images back to Kentucky.
