Get yourself a Photobucket account(free). Upload your photos, and select what you want to share...Then just click on their [img]-code link and it will copy the tag. Pop over here to a posting page and hit ctrl-V and it will copy the url and tags.
If you are sharing an image from another site, right click on it, and go to properties. Copy the URL under "Location", paste it to your post, and surround it with image tags, thusly...
EDIT: BTW, Welcome to BC.
What trim level/color/motor do you have?
