 Replying to [comment:7 mikeschinkel]:
 > This would enable a plugin author to write image image management tools
 that would actually know where the images are used. It would allow a
 developer to write SQL scripts to remove image records that are not needed
 yet keep ones that are. There are at least 3 distinct places in a recent
 project where I could have used this functionality. It's like asking why
 it's important to have a `post_id` field in wp_postmeta; without it data
 integrity is a challenge. I'm really surprised the use-cases are not more
 obvious.

 Exactly. I'm surprised at the reaction I am getting, this feature wouldn't
 slap your grandma ;)

 every time an image is uploaded it should receive an image_id number. Then
 every time you publish or updated a post it should scan it for what images
 are used and save their corresponding image_id to the posts meta data. Or
 something similar to that.

 reliable image management in the editor should be a basic goal not an
 exotic feature. External images may just be to bad, I don't see how that
 would work but then again you wordpress developers are geniuses to me so
 who knows!
