What You'll Need
You should have Zenphoto installed on a server and have access to the file system on the server. You'll also need to have a Fotomoto account. If you don't have one, you can Sign Up here.
Copy the Fotomoto Script
Go to the Settings page of the Fotomoto Dashboard, click the Get Script button and copy the Fotomoto Script.
Find your Current Theme
Log in to Zenphoto as an administrator, and click the Themes tab in the main navigation bar. Note the name of the active theme. The default theme installed in the 1.3.1 version of Zenphoto is called "Default".
Edit your Theme file
Go to the folder where Zenphoto is installed on your server, navigate to the themes folder, and edit the file that contains the </body> tag (normally image.php). For example, if you installed Zenphoto in to a folder called "zenphoto", the path might look like this:
../zenphoto/themes/[your-theme-name-here-default-is-default]/image.php
Find the </body> tag, paste in your Fotomoto script just above it, and save the file.
Success! You can now sell your photos!
Your Zenphoto site should now have the Fotomoto Buy Buttons added under every picture.
Please note that you will need to repeat this process should you decide to switch themes in Zenphoto.
