The key thing I think you’re missing is understanding that WordPress doesn’t use a linear path for saving posts. Because posts are autosaved you’ll want to handle this in a way that defines it according to it’s publish status rather than it’s save state.

Depending on the way your theme uses the_title, hooking into the the_title filter may or may not hide the title h1. What theme are you using? The the_title filter passes two arguments: the title (string) and the post ID. Therefore, treating the title as an array (it looks like you’re assuming $title is an array … Read more

Instead of the_title() try this: echo get_the_title($_img). It should only work inside the foreach loop.
