First of all, you should enter your License Key (Product Key) and then the BASE URL.
The BASE URL is the Internet address, where your book will be saved in a subfolder named after the book name.
The BASE URl plus the Book name define the Internet address, where your book will be found.
Click on “Help – Registration” in the menu and enter the license key in the registration window below.
The easiest and safest way to do this is to drag and drop or copy the license key from the order confirmation.
Afterwards you have to enter the base address (BASE URL) for all books managed under this License.
The base URL is automatically extended with the book name when creating an “Online Package”. Together BASE URL and Book Name build the complete Internet address (URL) of each book.
An “Online Package” is an automatically created folder by Mz3 Photobook. Once all files and folders for tehe Online Pckage are collected, the folder itself or the entire content of that folder (the “Online Package”) must be uploaded to the target server under the final Book URL (i.e. “base URL + book name”), using an FTP program.
BTW, the book name the same as the name of the folder, from which the selected photos originate.
Hint: If you only want to create and use Offline Books (books that are displayed with the Mz3 Viewer on a Windows or macOS PC), for the time being, you can enter any valid, i.e. existing and registered domain name, e.g.: https://acme.com, to finish the registration process successfully.
Whenever you are ready to create an Online Package, you should adjust the dummy BASE URL with the real Internet address, where you plan to host your book.
