I can't seem to get this to work. Most of the time, all I get is a link on the page to the SmugMug Gallery. A couple of times, I got the link, plus one small thumbnail that when I clicked on it, I got a message saying it couldn't access the service at this time and to check back later. (there are 71 photos in the Gallery)
Have checked the API key and it is good. Not sure what I am doing here.
