We have created a custom button on the Lead record to be able to easily send Lead information to non-salesforce users/Partners.  Where do I locate the link to the new email template so that I can link it to the custom button?

I can't seem to get my formula correct---

I want to have an image displayed if Named_Account__c = true

IF (Named_Account__c, IMAGE(servlet/servlet,filedownload?file=xxxxxxx"), 'blank")

and i get this message

Error: Incorrect number of parameters for function 'IMAGE()'. Expected 2, received 1

What am i missing?
