When I update my images, the new images do not show up in SimpleViewer. Why?
You may be looking at a cached version of gallery.xml. Browsers will save previously viewed versions of files on the web for faster loading. To avoid this, you can clear your browser cache after making updates. To clear the cache in Internet Explorer go to Tools -> Internet Options -> Delete Files, or press Ctrl-F5 to reload the page without caching. Visitors to your gallery will almost always see the latest version of your gallery. Most browsers check for newer versions of files on each browser session. Browser caching happens for all websites, so this issue applies to all files on the web.
