Desktop backgrounds can just be about anything. Almost all types of image files can be put up as wallpaper. Aside from the common .jpg or .bmp, you may also place other file extensions such as .png or .gif. You can put your pet’s picture on it, your own picture, your favorite place’s photo, your favorite movie’s billing, your favorite celebrity’s photo or some graphic design that you, yourself made. If you’re not contented with your own pictures and want to check out on some other wallpapers, there are also a million pre-customized wallpapers that are available online, and most of them are for free. Some websites are dedicated to giving users the best visuals arranged in categories for easy browsing.

If you’re the kind of person who doesn’t like seeing the same wallpaper all the time, and yet you don’t have time to change it as often as you like, there’s a solution to that problem. There is software that schedules wallpapers to change at a specified time and regularity. All you have to do is load the pictures that you want to shuffle, in the library of the software, and then set up the time that wallpapers have to shift, and you won’t have to change them yourself again.

The use of flash is very common on company websites. Design and media companies in particular prefer the use of flash because they want to impress visitors. Many newspaper and magazine websites also use flash to make interactive maps of places that are in the news.

Flash is the program used by web designers to make the pages, games and special files – or ‘movies’ – that this program creates. The movies are added to web pages just like pictures or other extras, like Java. When the page is sent from a web server to a browser, the movie file is sent too. The flash player, a special program, reads these movie files and displays them properly inside the web pages.

Although not a standard part of the world wide web, ever since flash was launched in 1995 it has become the most common way to add cool extras to websites. Many computers are sold with the flash player already installed. In fact, over 97% of Internet users have already got flash on their computers.

Flash gets a new version at frequent intervals, and you may need the latest version of the flash player in order to see pages created using it.

As flash animations have reasonably small file sizes, larger and more complex animations can be put online and downloaded reasonably quickly. They can also have interactive ability built into them, which is extremely popular for online games and special effects on web pages. The problem with flash is that it can make sites hard to look at and slow to download if it used too frequently.
