Asp.net Image Slide Question

I have 6 images and i want that when i will run my webpage it will display image in slideshow manner. and there is also two image button, one is "next image button" and other one is "previous image button". but these two image button will show on the main image when i put my mouse over it and it will act so that if i will click on next image button next image will be displayed and if will click on previous image button, previous image will be displayed. Remember that "these two image button will displayed over the main image when i put mouse over it"..
