You can't copy and paste the URL to a page the image is on, but you need to post the link to the actual image itself.
Looking at one of your posts you have an image like so:
http://www.fordrangerforum.com/album...pictureid=5218
That is simply a webpage with the image inside it, right click on the image and you see the URL is actually like so:
http://www.fordrangerforum.com/pictu...pictureid=5218
