Existing SMF Fourm-Admin Populated Photo Gallery---Bridging?

[Defensor]

I have an SMF Forum running already and recently installed Coppermine.  I, as the admin, created some categories, subcategories, and albums.  I have begun to populate these with photos (roughly 300 now).  I have not bridged the two yet.  The only user in Coppermine is the admin account.

My question is:  If I run the bridge now, will I lose all my photos?  I know I will not physically lose them all, but will I have to recreate all of my categories, subs, and albums?

I've read posts that indicate if you have users that have already established galleries and uploaded photos to them, they will be lost.  What if only the admin have created public cats, subs, and albums?  Will they too be lost? 

Thanks in advance for any replies to this post...

Please search again - only member galleries will be affected, and you can fix that by using phpMyAdmin.  Nothing gets deleted.  I've replied to several posts asking the same or similar question in the last week.  When an admin creates categories in admin mode, they aren't his/hers, they are public for the entire gallery.
