What You'll Need
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 Coppermine as an administrator at http://[your-site]/[your-coppermine-folder-name]/admin.php, and under the Gallery Configuration heading, click the Theme Settings link . Note the name of the theme. The default theme installed in the 1.5.8 version of Coppermine Gallery is called " Curve ".
Edit your Theme's template.html file
Go to the folder where Coppermine is installed on your server, navigate to the themes folder, and edit the theme.html file in the folder named after your active theme. For example, if you installed Coppermine in to a folder called "coppermine", and the theme name was "curve" the path would look like this:
Find the </body> tag, paste in your Fotomoto script just above it, and save the file.
Success! You can now sell your photos!
Your Coppermine 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 Coppermine.
