Pin-it Button loading in same window & image not working

Pin-it Button loading in same window & image not working

I while back I created a custom little div tag that make it possible for
me to put a pin-it button over another image. Recently Pin-It has changed
around their website and recently we upgraded Joomla 1.5 to Joomla 2.5. I
am not sure where it went broken however...
The Pin-it image is no longer working and is showing a "1" instead. Even
putting in the code straight from pin-it website doesn't load an image or
the pop-up correctly.
Can anyone tell me if there is a problem with 2.5 Joomla and Pin-it? Or is
Pin-it broken? An example is below...its the "1" that's right under the
dog on the red stretcher image.
