Adding a picture to a web form

 I have a very simple question and I haven't found an answer. Maybe it's a stupid question.
I have a web form that uses a master page. I want to add a picture to it. The picture is on my hard drive. The picture should go in a content place holder, and it can simply be static- no dynamic display code needed. I tried drag and drop but the image didn't display properly. I also tried adding an image from the toolbox, but could not get it to point to the image file.
 
Thanks in advance,
