In the new photos app, how can photos be deleted from device independent of import time? I go to photos app.
I DO NOT select "Delete after import" (for the purpose of seeing if it mattered).  I import photos from iphone. 

Now I havent found an obvious way to go back and delete all of the just imported photos from my device.
If anyone has a way to do this that would be good.
If you do not want to deal with this, select "delete after import" when you are importing photos. This is for if you forget to do that.
Easiest way is to use Image Capture from OS X

You can use it to Import too, to any app that can import pictures, or to a folder location.

Select any pictures you wish to delete &amp; hit the 'no entry' sign to trash from your device
