Chris, I know it is frustrating to fiddle with this computer stuff when you'd rather be wrenching, but I'll stick my neck out and offer some suggestions:
To display an image (photo), you need these two "tags" [img]and[/img]. They tell the computer that there is an image address located in between those two tags. You must not have any additional tags - just one at each end. You are welcome to click that Img button when you want to post an image, but make sure you are left with only the two tags and the address in between.
So your: [img][IMG]
http://i708.photobucket.com/albums/ww88 ... eesome.jpg[/img] has a stray tag at the beginning. Get rid of it, and the image shows up fine, as pope shows it in the previous post.
As for opening several "windows", I bet quite a few forum users don't realize that you don't have to constantly go back and forth. When you click on any "button" or "link", just hold down your "shift" key at the same time, and the link will open a new (second, third, fourth, etc...) window. So, for example, when you click "Post Reply", it will open a new window for you to write your post. Then you can move back and forth at will, closing windows when you are finished with them, or can no longer keep track of them.
It is also generally faster, because when you click ''back", you are forcing the computer to dredge up the previous page, and in some cases you are forcing it to actually re-download that previous page. This way, you are keeping all the relevant pages "open" on your "desktop".
Clear as mud, I know
As an example, I open a separate window each time I look at an active topic, so that the list of active topics remains open on my desktop. Otherwise, if you simply used the "back" button, the llist of active topics page would actually be re-downloaded every time ! (In fact, you will want to "refresh" that active topics page from time to time, so you can see what is being added to it.)
The key to this is holding down the "shift" key when you click on a link or button.
Hard to explain this stuff, but I hope this is a help.
By the way, my vote is to keep the cars (at least one of them) stock, but unless you are aiming for concourse quality, go for generally stock appearance and modern or convenient mechanicals.
