You check them in their warm spots like under their wings. I like to check under their hackles. When you move the feathers to check, you need to be constantly watching because they like to hide. Also, be sure to check more than one hen. It is still safe to eat their eggs, though I don't...
Alright, that's probably your issue then. Try uploading them directly from your cellphone. If your phone doesn't have internet, then I would plug a cord into your phone to your laptop and upload them onto your laptop and post them that way.
Are you on a laptop? If you are, go into your PC folders, click the checkbox on the wanted image, and at the top of the screen there should be an option to rename the picture.
How did you upload the picture onto your device and what camera did you take it with?
