That’s going to be tough to figure out. I’ve had issues with prettyPhoto in the past doing something similar. I ended up just not using it since I could never get it to look right in mobile view. I noticed that Wes is slowly fading it out of his themes since it doesn’t work as elegantly when it comes to mobile. It could just be a prettyPhoto issue itself rather than the theme, since I’ve used it on another theme and had the exact same issue.
