Image page issue (attachments)

I am having an issue with an error on the bottom of my image pages.. Fatal error: Call to undefined function inkthemes_posted_in() in /home/brazilag/public_html/wp-content/themes/squirrel/attachment.php on line 78

I am using the Squirrel theme if that helps

Below is the code for the file that contains the error (I think) – attachment.php
