I wanted to do more. Keep the original wedding album and have a new light blue one. Copied the folder. Placed the new files in it. Renamed the folder. See both a blue and a pink Wedding Album thumbnails in Magic Style with the same name. Both of them previewed with the new blue contents. Looked at the xml documents and do not see anything obvious. Change the name in the desc_u.ini to no avail.
It looks like a backup of the original Wedding Album folder is desired. A pink original theme is available when the new blue one is removed. The new blue theme is available when the blue one or both folders are present.
Looking for ideas on modifying a magic style template and then save it as a different template in PD successfully!!!
