I copied my gallery to another to automaticlly renumber the photos within the gallery. Once I was ready to delete the copied gallery, I accidentally deleted the original. That did away with both of them, much to my amazement and dismay! Some of the images had been transferred to my other galleries and were easy to get back, captions and comments intact. Others need to be uploaded again, and I will do my best to recreate the captions... What a major goof. I hope this type of thing does not happent to anyone else.
