Both on the web and on my personal library has the same results. Whether it be through safari, firefox, or chrome i still have this issue. Very irritating when I'm trying to design a website!Are these images you are trying to view on a web site or through Photos? If it is on a web site, do you have content blocker on?
Yes, safari and computer have been restarted.Now you should quit Safari, then start it up. Those images should show up.
"No Issues Found." Reference code ADP000Is your System Preferences/Displays pref pane set for default resolution (and NOT a scaled setting)?
Can you log in to another account, and check if the images are still the same?
If you don't have another user account, this would be a good opportunity to make one, just for troubleshooting this issue...
If none of that helps, you should run your built-in diagnostics - https://support.apple.com/en-us/HT202731
Come back with any reference codes that might be generated by that test.
