First, login to your site. Choose a gallery. Once inside that gallery, choose the My Zenfolio button @ the top, and choose 'Customize Visitor View'. You'll be in a familiar looking page, but it is gallery specific. Choose the Options menu, and if you uncheck the "Use Default Settings for Layout, Themes and Options", all the settings in the menu become available to edit. At the bottom of the menu, under Thumbnail Display Options, you'll see three options (below the Thumbnail size choice box):
Title: Show/Hide
Access Control Icon: Show/Hide
Sequence Number: Show/Hide
I have the first two to Show, and the last to Hide. Then simply save this as a Global Preset, and all your other galleries should display titles and no sequence numbers, as long as they are all set to the new default settings.
hope that makes sense...
