More flexibility for in-post image selection heuristic

[nekohayo]

The "image selection" setting has the following choices:

• Any - Will look for 1. Featured Image, 2. First attached image, 3. First image in post itself
• Attached Only - Don't look inside post content for image
• Featured Image Only - Only use Featured Image
• Only show image for Media Posts - Don't show image, unless the post itself is a media post

But all the options other than "Any" are kind of fake choices in the sense that "Any" already does their job in most cases... but the sad part is that there is no flexibility for the "any" case. Personally, I almost never use the "Featured image" feature in Wordpress because my theme would display it above the post's contents, and I sometimes want to do that but most of the time not.

The problem with the "Any" approach's current heuristic is that I have zero control over what will get displayed; it seems as if it picks "the image with the newest upload timestamp" (this is a wild guess)... and I would rather like to be able to tell WP Tiles to get "the first image in the blog post [in the absence of a featured image] ", that way at least I would have more control over which image gets picked instead of trying to "plan my image uploads so that I upload the one I want last".

Either that, or a way to identify an image as being the "kind-of-featured-but-not-actually-featured" image inside a post, only for WP Tiles. Either with some tag/code in the image's inline metadata, or maybe with some setting pane in the post/page editing sidebar?

Thanks!
