You should upload the required image files (e.g. visa.jpg, mastercard.jpg) to skin/common_files/images folder via FTP or
admin back end and add something like:
Code:
<img src="{$ImagesDir}/visa.jpg" alt="Visa" />
<img src="{$ImagesDir}/mastercard.jpg" alt="Mastercard" />
to the "skin/common_files/customer/mytemplate.tpl".
And add inclusion statement into the "skin/common_files/customer/right_bar.tpl" template:
Code:
{include file="customer/mytemplate.tpl"}
