You've got the link posted. To make it automatically show up as a picture, you have to wrap the link in IMG tags.
Try editing your post and putting {IMG} right before the link and {/IMG} right after. BUT! Use square brackets instead of curves ones. I only used curved brackets so that it doesn't confuse the forum software into thinking I want to post a pic.
The cars just keep getting better and better, this is going too really make choosing wheels and tires hard. All of your rides look awesome. Thanks for posting them and i hope there's more too come.
