One tap opens the full Tour as a menu — 25 tiles with checkboxes. Tick the slides your talk wants and add them; SELECT ALL brings the whole Tour.

Or paste any image URL from the site — or leave the picture empty and give the slide a doorway below: the Lectern will use that page’s own banner automatically.

Enter any page on the site. The Lectern shows each section’s name with its real image — tap the ones you want and they become slides, each carrying that section’s own picture and a doorway to the page.
