if it can help…

“Later I convert them again to kml files with PhotoOverlay software. This kmzGoogle Earth File file is my finished product. ”

What PhotoOverlay software did you use to convert the images to KML? I’ve been looking at 360cities.com, but I want to be able to host the images locally as you have done.

You work looks great!

I invite you to come visit a new site called realplaces.com to see if it strikes your interest. Our purpose is to allow *anyone* to create virtual “walk around” tours, such as you have created, independent of Google Earth or StreetView. We use individual stills rather than fully stitched images, but in doing so we have other advantages instead, such as zoomed views that are independent of the original view, and descriptions and comment streams tied to individual views. You can write detailed information about each individual view, and even more importantly, other members can comment on your places as well. Hopefully this results in engaging and interesting conversations that currently don’t happen inside StreetView.

We have just opened up to allow a limited number of users to come and give it a test drive and see what they think. I welcome you to be the first member from Taiwan!
