Adding multiple images to appropriate rows.

I have a asp.net program, in which I have image field and id.There are so much items are there. So I Need to upload all the images of students according to their id at one click.

I have id in the range like 1,100/1,1001/2 like that. Images are in another folder with name 1.jpg,100-1.jpg,1001-2jpg. Is there any code to add each images to the appropriate ids easily.
