• Then once you have done that you want to click on Manage your Storage Space : 

• Once there you have to Click on My Attachments and make sure the group that you  want to delete pics from is selected.  

I had nothing there to show but if there is you will see every files name.  All you have to do is put a little check mark in the box or boxes and then you will see a little delete at the top.  Delete the tags that you want to I all way delete stuff that was posted a week ago or so on.
