In addition to delivering the photo links via email (which is the default delivery method), you can also choose to show the purchased photo/image links on the “Thank You” page (a post-payment return page).
Step 1) Go to the following interface and enter your PayPal PDT Identity Token
WP Photo Seller -> Settings -> Payment Gateway Settings
Enter your PayPal PDT token value in the “PDT Identity Token” field.
If you don’t know how to obtain your PDT token from PayPal, then read this instruction.
Step 2) Go to the following interface of the plugin and enable the “Display Download Links & Purchase Info On Thankyou Page” checkbox.
WP Photo Seller -> Settings -> Advanced Settings
Step 3) Edit the thank you page and enter the following tag in there (this tag will show the links after purchase verification)
{product_link_digital_items_only}
The plugin creates a “Thank You” page for you when you first install the plugin so just edit that page and insert the above mentioned tag. You can find this page in your Pages menu of WordPress.
