Fixed Inconsistent Behaviour Between Widgets

When clicking on an image in the recent comments widget, it loads the full gallery page, then the overlay on top.

This isn't consistent with the recent photos/videos widget where the overlay loads over the current page, which doesn't take the user away from whatever page the widget is on.

This is much better, as otherwise when they close the page they've been moved to a whole new page they've not seen before instead of back wherever they thought they were.
