ashwani,
Thank you – I didn’t ask the question quite right – when I created a carousel the first time and uploaded each image I did not create the url for it. Later, after I had all of my images uploaded I tried to enter a url for each image and I couldn’t get it to update. I tried again – created a new carousel and entered a url for the image as soon as it was uploaded. This seemed to work, although I haven’t tried to change or update any of the url’s yet.
Anyway, I think my problem is solved, thank you for trying to help me.
