The photos in your home page gallery appear on your computer after being saved to your computer’s browser cache. This means that a copy of the gallery is being displayed each time you visit your web site. The same is true for each of your visitors. Therefore, any changes you make to the gallery will not be visible until each person viewing the gallery clears the cache on his/her own computer. To get around this, the web site will force a refresh of the gallery every seven days to ensure all visitors see your latest changes.
