Yes I need to be logged in to see pics also. Who is your carrier and what is the signal strength? You also may see slower loading from some photo hosting sites if you are a)moving (i.e. in a car) and changing towers. If you are stationary on 4G or WiFi it should work flawlessly if you are logged in. I always log in because my theme is blacked out. The white background of the site hurts my eyes after a long day.
