image not displayed when executed coldfusion

Hi developers,
I have created one cfm page and where in i am calling an image into a table cell . the image is actually stored in my coldfusion server in a folder called "image".

when I execute the cfm page from localhost:8500/.....cfm, the page is getting loaded perfectly but the image is not displayed but an image icon is displayed with the image name. plz see the attached file.

If I see view source of the page and save the code in a notepad with aaa.html, and saved i in desktop and executed, and now image is displayed. i dont understand why?

The image code:
 
<td> <img src="C:\ColdFusion8\wwwroot\sitename\images\sample.jpg"  />
