It looks like your images have not been uploaded to the correct location on your web server.
According to your gallery's XML file (http://garylordjohns.com/JuiceBox%20Gallery/config.xml), the first image in your gallery should be located here: http://garylordjohns.com/JuiceBox%20Gal … adshot.jpg
However, going directly to that location in a browser results in an error 404 (file not found).
(Your gallery uses a baseURL and, therefore, any relative paths in the gallery's XML file, such as the imageURLs, thumbURLs and linkURLs, will be relative to the baseURL.)
Check that your images have been uploaded to the http://garylordjohns.com/JuiceBox%20Gallery/images/ directory on your web server.
Please also see this FAQ for further suggestions:
My images show locally, but not when I upload them to my website. Why?
Also, the name of your Juicebox gallery folder ('Juicebox Gallery') has a space in it. I would recommend using only web-safe characters (uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde) for files and folders on your web server.
