Some of the readers who have not delved into Web designing, may be wondering as to how the above picture has been super-imposed with flying birds. In fact it is quite easy.
All you have to do is have a suitable image for background and an animated GIF (Graphics Interchange Format). With these two things at hand, you will be able to achieve the above affect by writing just a small HTML code. In fact, I am providing the code for this example in the box below, which you can copy and paste in your own Web page. Of course, you may decide to experiment using your own background image and GIF.

Just "right-click" inside the Text-area and "Select All", then
"Copy" and "Paste" to your Page!
