Picasa photos in gallery don't show up in photos app or google+ photos

I have some photos that show up in gallery>picasa, but not in the photos app. I know these photos were downloaded pictures from a previous phone, off a received email I believe. I may or may not have deleted them before on the google+ photos list on the web. After switching to a new phone with the same SD card, they are still there, unable to delete in gallery because they supposedly come from picasa web. Please help.
