Thanks for the mod LouOffroad, works great. I used the new bottom corner COMODO logo, bottom right and the code i used was to pick up the logo from my main site images.
skin1/customer/home.tpl - Just before the </head> place:
Code:
{literal}<script>
var cot_loc0=(window.location.protocol == "https:")? "https://secure.comodo.net/trustlogo/javascript/cot.js" :
"http://www.trustlogo.com/trustlogo/javascript/cot.js";
document.writeln('<script language="JavaScript" src="'+cot_loc0+'" type="text\/javascript"><\/script>');
</script>{/literal}
Then at skin1/customer/menu_cart.tpl - After the last </if> and before </capture>
Code:
{literal}<script language="JavaScript">COT("https://www.shisha.co.uk/images/cornertrust.gif", "SC2", "none");</script>{/literal}
This points to the image cornertrust.gif in my main images folder.
The cornertrust.gif looks like this, you can right click it and save the image
http://www.shisha.co.uk/images/cornertrust.gif
You can see the finished page at
http://www.shisha.co.uk/shopcart/home.php
You can see it is at the bottom right and always stays there no mater how far you scroll down the page
