When i was using this code, the first image only it shows. But i am using the another way for storing the image in filesystem(i.e. store the image in image folder under the project root folder), Then we get those images and provide the slideshow with all those images. The code for this functionality, it's working well.

You have JavaScript errors which are stopping execution.

The very first word "Begin" is inside an HTML comment, but it is NOT inside a JavaScript comment. This crashes JS right from the start.

Also, newer browsers ignore EVERYTHING inside the <!-- --> comment tags. JavaScript inside these will not even start on some of the newest browsers. It is better to have an external script file.

Please put your code in [ code ] ... [ /code ] tags when you post (remove the spaces I put in to make them visible). Then the code is more legible.
