The Upload Your Logo feature only adds a custom logo/header to your checkout pages (for payment processors which support it), E-junkie thank-you pages, E-junkie Marketplace Shop pages, and the "fallback" version of our cart that appears in a new window/tab if JavaScript is disabled.
There are technical reasons why we cannot simply insert any custom images into your overlay-style cart from our end. However, you can accomplish that yourself by adding the following lines to each page where you are using our View Cart code, just before the // --> line in the standard code we issue:
function EJEJC_config() {
EJEJC_POSTCALL=true;
}
function EJEJC_shown() {
jQuery("#imgHeader").attr("src", "http://www.yoursite.com/path/to/logo.jpg");
}
If you are already using function EJEJC_config(){} in order to customize your cart, then just add any new lines shown above which are missing in the code you already have.
