Mary,
These are the posted instructions.
"To replace this quilt with a different one, click the "Delete Quilt Profile" button at the bottom to delete this one first. Then, add the new one from scratch so the Quilt Gallery will reflect the date the quilt was added and it will be assigned a new quilt number. Otherwise, you simply will be updating this current quilt."
I guess you changed the image and did not delete the previous ones. I recall others having the same thing occur.
Good luck.
