I like the idea of Gravatars, and they are easy to implement in PHP, but I cannot execute straight PHP code, only Smarty Templates (under Blogsome). I’d like to be able to write a Gravatar plugin in Smarty Code, but I don’t know how to MD5 encrypt just in Smarty. I thought the following would work, but it doesn’t seem to: {php}echo md5("email@address.net");{/php} In fact, I can’t seem to get any code to execute using the {php} {/php} tags. {php}echo "Hello, World";{/php}
