The occasional page was fed a gif or two, but these were generally small simple pages with small and simple needs. Every day, new and different things can be added as web page fodder. There are disadvantages to such additions. Many sites have yet to understand how overfeeding a page can render it useless. Too many animations, too much embedded information and people get bored with waiting for the web page to waddle its way down to the browser.
Some web pages are dependent on their looks to inform people.
These pages are useless to many who refuse to see the picture and wish for some text based information to be passed their way. The other things certain sites depend on is using all of the latest and greatest bells and whistles on their web page. Unfortunately, unlike normal bells and whistles, the ones on a web page generally require that those who wish to view the page to download something to their computer. Worse, they may well have a difficult time finding and getting the new items, therefore never properly visit the web page that requires them. Then there are those demanding web pages.
