It may be my personal preference, but I really like having the “Featured Image” metabox up at the top of my screen. I use it almost first thing on every post I write, so I don’t like searching for it. This plugin will force that metabox on top for the “post” post type. 
There’s only one option available, in the regular Media Settings page. “Allow Users to Customize Order” which is ON by default, can force users (if off) to have their “Featured Image” metabox stuck to the top.
Feel free to contact me, emrikol@gmail.com, if you have any problems or questions.

This plugin aims at providing users the capability to upload multiple thumbnails/featured images to a post. It uses wp.media js object to open a image uploader frame and choose/upload images. Once the images are selected, it will save the id of uploaded media object in a custom field.
<h3>Getting uploaded images</h3>
You can use the function aoc_get_images($post_id) to retrieve an array of urls of all the images that have been uploaded to a post. This function accepts the id of post (for which the images are to be fetched) as a parameter.

AOC Multiple Post Images
