Please correct my terminology.
Magento apparently allows "pseudo-code" like this in email templates (and elsewhere I suppose):
{{htmlescape var=$order.getBillingAddress().getName()}}
It mixes right in with the html to create dynamic output.
Now, I know you can do this in php to get the logo src:
<?php echo $this->getLogoSrc() ?>
Is there any way I can do this in the email templates? Every time we change our logo, we have to change the hard-coded img src in the email templates as well.
