· Uploaded images are saved to viewer/plan/，and written into tour.js; refresh to apply.
· Use a top-down image with the long edge horizontal. Pins are stored as a ratio of the image size, so they keep the same relative position.
· Changing the image never deletes the old one — you can switch back any time.

· Leave the link empty → the title is plain text and not clickable.
· The exported read-only version keeps the title and link too — clients click the title to reach your site.
· Remember to click Save in the top bar when you’re done.
