Slideshow of collection of dynamic images using C#.net

hello friend,
I have done like this , i can give you idea to do this :
one solution is to bind images in datalist (like thumb image of gallery category), when you click on that then open it in another div in larger view set z-index of that div in style. and in that div bind another datalist of particular type images (acc. to your requirement) and use marquee tag to scroll images in any direction or paging to click on next or previous image.

Hope you get that the solution.
