Where is the option to unattach?

Hi handhugs,

I had the same problem until I worked out that I had the media library in the wrong view.

What you have to go to media library and in the top left of the screen near the drop down fields you will see two little boxes one shows four little boxes the other shows lines, choose the ones with lines and this will put the media library in list view, from there its just a matter of clicking on Detach to un-attach whatever image you want.
