Auto-fill post_title for WordPress pictures
WordPress is so good for SEO in part thanks to the large number of data fields available for each post: post title, excerpt, name (slug) and, finally, content. This allows for deep customization when presenting your post to the WWW.
While it’s fine to fill all those fields for a regular article it may be an overkill for a picture for that same article (which is just a sub-post in terms of WordPress built-in media library). (And even for a normal article – how many of us really do enter post excerpts? Yes, that’s what I’m talking about.)
