Image in Template Troubles

I’m working on a child theme to TwentyTwelve, and I’m trying to display an image on the template. I am using this tidbit within the img tag…

<?php echo get_bloginfo('template_directory');?>

…but it’s looking for the image in the parent theme instead of the child, and so the image isn’t displaying. I need it to pull from the child directory.

Is there a different bit of code I should be using, or an alternate way to set it up?

Thanks in advance.
