When writing post or page you can click Add Media and on Insert Media tab you have drop-down menu first two options are "All Media Items" and "Uploaded to this post".
I am looking for any way to make "Uploaded to this post" default option. I am open to any solutions that will work even editing source files for WordPress directly.
So far i only found jQuery solutions that work very slow first letting 200 images load and only then switching to "Uploaded to this post".
I assume it could be faster if i can limit images that load by default to 1 as i don't ever need to see all images anyway.
