hi, 1stly sorry for my broken english. hehe..
ok, i have some contributors on my site. when my contributors want to create a post, they also want to upload a featured images too. So, how to make all contributors can't see others contributors image file?
Contributor A was uploaded 2 images.
Contributor B also want to upload his own featured images. Suddenly when he want to upload, he see a word Media Library. so he click on it. Unfortunately, all images from others contributor also shown.
so how to avoid this?
