[RESOLVED] Assign Resource Image files to large number of Picture Boxes via code

I added about 100 images to my project as Resources. They were named "01.jpg," "02.jpg" etc. up to 100. After adding them, they became "_01," "_02," etc.

I have random numbers generated, and want to assign that number image to a picture box accordingly. When I do it at design time, it's like this:

Is there a way that I can use the random number generated (in this case "1") and choose resource _01 as a result?

Please let me know if that doesn't make sense, thanks!
