I've tried to upload image here from phone & it's says it has an invalid extension. If I plug the phone into my PC & browse to them from there they upload fine. They were PNG screenshots. I'm unable to upload jpegs too - doesn't error - just don't appear. If I choose 'from camera' option it takes the picture, leaves the new post I'm on & opens another new post but the image doesn't upload. Android. Any idea's please?
