deleting images when deleting post

I think it is not possible. You will need to search in the media library for the images that are not associated with any post..

well. this is just meanless.. my blogs will have 50~ photo for each post and sometimes posts need to delete.. i dont want to search tons of photo every time i “just” want to delete a post -.-‘

btw a plugin solution is welcome too

aww..
there must be a solution for it :-/
