Images in My Portfolio are not displayed.

Thank you for your reply, the image not showing has nothing to do with clearing the browser cache, as I have a habit of exiting the browser to clear the cache by default. I've tried to replace different devices, computer phones, etc., including internet logins at work or at a friend's house, and the pictures don't show. As for the Iron Man image, I know it's due to copyright issue, I put the Iron Man image to say "Clicking the Uploaded Files button will display several types of images (including New, In review, Reminder), but clicking the Dashboard button will not display them", assuming that if it's a network issue then no images will be displayed, not a certain location will display them normally, therefore the network issue is ruled out. I asked other contributors and found that there are many contributors in some Asian countries who have the same problem as me, but not outside Asia.

Thank you very much for your reply, unfortunately it was not caused by a problem with the internet.
