Very good work Eric!
You've done a lot of work once again to bring that project to us.
I cant thank you enough for your attention to detail in documenting the photos you take on your tours
You don't need to resize the photos. The software makes a copy - suitably sized for publishing - when you click the Generate button to create your web project. The copies are placed in the folder you drag up to the server.
It also makes a thumbnail of each of your photos which are displayed on the right of the main photos on each HTML page of your project.
No need to worry about the technicalities folk - all of the above is done completely automatically.
