Getting image data from local folder in windows

I have two hosted website on a server, Main site and secondry website which is used to load images.
Right now i am using url of secondry site in main site to get images, and showing them in grid.


I don't want to move further with this procedure of two websites anymore and want to load images from local drive so that i can have only One hosted website in iis...
any another solution will be good also?

Thanks in advance
