I used the Camera App that came on the phone to take the pictures. Usually all my photo's upload to my +Google account, but copies stay on my phone. Several that I am trying to send by email are ones that did not transfer to the google account. It's as if my phone selected randomly from my gallery a bunch of photos to upload. When I try to attach the picture to an Gmail I get the message "Unable to attach". When I try to attach the picture to Yahoo mail, it says it's not able to and that it thinks there is something wrong with the APP (referring to the Gallery APP). I noticed recently too, when I tried to play a video I took, it said it had to download the video first, but I only use WiFi and I was in a dead spot so I couldn't download it. I don't remembering uploading the video. I'm guessing the pictures in the same place maybe.
