I have a Google sites website that has contains photos and a little text. I have been gradually adding photos to it over time. When I went to open it the other day I found many of the images had become blank white boxes with a small red X in the upper left hand corner. I tried right clicking "show picture" but that doesn´t work. Some one on another computer said they checked the site and can see the images just fine. Why can´t I see them anymore on mine?

This is the page:
https://sites.google.com/site/colombianaturesite/nature-images/birds

Clear your internet cache as they are appearing just fine.

Thank you I´ll try that.
