Asp.net photo gallary

Hi all,

I am a new bee in asp.net.

I am developing a website for a trust where i have a photo gallary page.

I have a datalist control with image buttons in it where photos are saved in folder and photo file names are retrieved from sql database.

Problem:
1) I want to allow user to click on the images in datalist
2) When user clicks on the image button i want to fade the webpage and open photo in its orignal size.

Can anyone help me on this, i have browsed through the net for this and got some examples but none of them worked for me.

Request you to explain me you code so that i can sharpen my knowledge.

Thanks in advance.
