How can I remove photos from an iPad Min without having to restore it? My iPad mini is overloaded with pictures.  I would like to delete them without having to restore the device and lose years of my iBook annotations. Is there a way to get these photos off my iPad mini without having to restore the device? I wish Apple would make it easier to simply delete photos from an iPad mini, but until that day I hope you can provide some options for us.
What you ask it trivial on iOS 9. Enable cloud photos in iCloud settings if you haven't already. Once it's synced, turn of the library. 

Select Remove and you are done. 

If for some reason you can't or won't do that, connect to a Mac and you can use Image Capture app over USB to bulk delete. I suppose a PC version of the tool would exist, but that's not my area of expertise. 

Also, you can select entire moments to delete on iOS 9 so even the manual method isn't a 1 to 1 tap to delete operation.
