You might notice that after your photos has been uploaded, you still cannot see the changes - this is because you must use your browser's refresh button to see the changes. When you go to a website your computer stores the page information into a temporary cache memory file so that as you scroll back and forth between pages your computer does not have to go back to the web server and “get” the page you were just at.
So if you don’t “refresh” after changes have been made, your computer might be readying the older version stored in your cache memory and that's why you can't see the new updates!
So always remember to refresh your browser.
HOW TO REFRESH YOUR BROWSER
Just click the “refresh” or “reload” arrow button at the top of your browser window so that it will load the most recent changes.
If that still does not work, you might have to try a "force refresh" which will cause the browser to re-check with the web server to make sure it has the latest copy of the web page you are viewing. Just hit the control (Ctrl) and F5 button at the same time (Windows). Or, if you are using a Mac - Apple + R or Cmd + R.
Still not working? You may have to clear your browser's cache. Choose your browser from this list: http://www.wikihow.com/Clear-Your-Browser's-Cache and follow the instructions!
