How do I remove offline photos from Photo Gallery when the originals erased?

I was caught off guard with this new Windows Live Photo Gallery.  On my pc, I just wanted to edit a photo on my phone, but I forgot that my photo must be on my pc in order to edit it.  Upon opening Photo Gallery, it started importing all photos from my phone.  I thought now is a good time to get them off my phone.  I let it run and it proceeded to erase all original photos so I have none of them in my Windows Explorer.  In the middle, I was going to cancel the erase (I was not aware they were going two places - online and to Windows Explorer.  I thought my photos were only erasing from my phone).  Now Photo Gallery will not open due to offline files.  How do I remove them if they are not in Windows Explorer or on my phone?  Where are they?
