Error on Blog Post Page After Activating Plugin

Hi there,

I just installed and activated the plugin, however, there are errors showing up in place of the images in my blog post.

The error message is Warning: sprintf() [function.sprintf]: Too few arguments in /home/multifo1/public_html/wp-content/plugins/pinterest-pin-it-button-for-images/ppibfi_pinterest.php on line 236

Could you let me know how I can rectify this?
