In the beginning internet was not so interesting, the way it is in these days. At that time we used to see hardly a picture in website of black and white backgrounds. Most parts of the website were just texts. With the pessage of time, web techologies are developed and websites are becomeing more beautiful and interesting. First sites were used for transmitting messages, then people started using for commercial and marketing purpose in their business. Web designers and programmers started developig techniques to make the website more interesting through picturers. First bitmap, then jpeg, gif and png file format were used to compress the size of the image so that it can easily be downloaded.
To make the website interesting and beautiful , programmes and tools were developed among which Adobe flash (formerly known as Macromedia Flash) is the most powerful tool.
