When setting the above to a Custom Image Folder on Server, what is the proper syntax to be used for the Image Folder Path ?   Should the Image Folder Path be a URL, such as "/MRS/CustomImages", a file system path such as "c:/CustomImages".   What works here ?

Also, how is the image file selected ?.... which .JPG file is used within the custom image folder ?..... A bit more HELP information is needed.
