Need Help with this smarty

I am newbie & trying smarty for Gravatar plugin like开发者_开发百科 this.

<img src="{gravatar email="example@example.com"}">

But to get value of email I need to use {$client.email}

So My final code look like

<img src="{gravatar email="{$client.email}"}">

Which is not working.

Where I am going wrong ?

Thanks

I think it should rather be something like that:

<img src="{gravatar email=$client.email}">

However, its been a while since I last used smarty.

Be sure to also check the online documentation for smarty -> http://www.smarty.net/manual/en/
