To resize photos. Are you using a computer? Quickest way is in Paint in windows 10. You just click on "resize", select "pixels" and set the top set of numbers to 650. the bottom set changes automatically - then "save as". that's the right size to upload and fit on the forum page

If using a phone or ipad it needs an app.
Our first hamster was about 6 feet away from the side of the TV (cage on the floor) and no issues. TV on most of the day here too when the child is in the house. It is better if they aren't too near a TV - might mean moving the furniture round a bit!
