is there any way to make it go to the page with the larger version of the image the FIRST time you click the image and not the second? It seems redundant to have to click on the image over and over again to get to the larger version of it – thanks in advance for your help!
But here are a few things to look for. First, the page that you’re seeing on your second click is the image’s “attachment page,” which is generated by the Media Library. So, what you want is a way to display the attachment page as a post, which I can’t figure out either (sorry!).
You could create a child theme to Twenty Twelve and define a new post type that mimics the attachment pages – that’s probably the easiest thing. But I’m sure others may have better ideas.
