Class ID or Element

Hi, your plugin is great. I have been using it to trigger via comments, however it is too far down the page, so I tried the percentage, which works well, but then the popup appears on my front page – I only want it to appear on my blog posts. So is there a way of triggering I scroll to a certain image, I will place below my post content but above my comments. Please advise.
