Actually, if you do a view source on your page, your gallery image has the following:
<a href="https://www.therisingspoon.com/2013/03/how-to-make-homemade-meat-stock.html" onclick="javascript:_gaq.push(['_trackEvent','outbound-article','https://www.therisingspoon.com']);" target="_blank" class="set-target no-lightbox"><img width="150" height="150" src="https://www.oursmallhours.com/wp-content/uploads/2014/01/155-150x150.jpg" class="attachment-thumbnail" alt="How To Make Homemade Meat Stock" /></a>
But looking at it with “Inspect Element” I see the following:
<a class="set-target no-lightbox" target="_blank" href="https://www.oursmallhours.com/wp-content/uploads/2014/01/155.jpg" rel="cyberchimps-lightbox" onclick="javascript:_gaq.push(['_trackEvent','outbound-article','https://www.therisingspoon.com']);">
<img class="attachment-thumbnail" height="150" width="150" alt="How To Make Homemade Meat Stock" src="https://www.oursmallhours.com/wp-content/uploads/2014/01/155-150x150.jpg"></img>

Assuming “https://www.therisingspoon.com/2013/03/how-to-make-homemade-meat-stock.html” is your custom link, it looks like you have something modifying the links post-page-load via javascript. When I disable javascript, reload, and view the source, the html link is still there. It looks like you have a conflict with another plugin, would be my guess.
