Image Placement

I am new to Word Press and appreciate all of those helpful people out there. My question deals with image placement. I want to be able to place an image to the left of the content area, then type the text around it, starting at the top/right side of the image. As I type more and more text, I want the text to start placing itself to the side of the image, eventually going under it. I hope I explained this correctly. Thank you.
