When the Return Method is set to “Direct Return”, your Approved URL page will be fetched and displayed to the customer while they remain on 2Checkout’s server. Because of this, images and links that use relative paths will not resolve correctly, resulting in broken images and incorrect link destinations.
To fix this, you will need to specify a base URI for your Approved URL. This can be accomplished by inserting the following line between the <HEAD> tag of your page:
<base href=”http://www.example.com/pathto/approved.html”/>
The URL specified after ‘href=’ should be changed to your Approved URL.
