Wow, that's a very nice truck. Mine also seems to have been a CA truck it's whole life, but has some floorboard rust issues... I hope yours doesn't, I didn't even think to look there with no holes elsewhere.
For pictures, I'd suggest uploading them to
www.imgur.com and then img tagging them here. A feature of imgur that most sites don't have is that you can put various letters immediately before the .jpg to resize them, so they aren't huge. h (for "huge") is the size I typically use, I think it's 1024x768, which is a reasonable size for forums. l (for "large) is 800x600, a little small for today's monitors.
http://imgur.com/yWP94kU is a picture of my truck that I uploaded. To the right of the image, you'll see a Share This Image section. You'd need the BBCode option, which is:
[i mg]http://i.imgur.com/yWP94kU.jpg[/img]
or, the smaller "h" version
[i mg]http://i.imgur.com/yWP94kUh.jpg[/img]
For both of those I put a space in the middle of img, to not clutter up your thread with pictures of my truck, and let you see what's written. Without the space (as they appear after uploading), they'd appear as images.
