Here are some that I threw together. Feel free to use them.
To put one in your signature:
1. right-click the image you want to use and copy image location (Firefox menu anyway)
2. Go to your 'User CP' in the link at near the top of the page
3. Click 'Edit Signature' on the left menu
4. Hit the
button above the reply box
5. Paste the image URL you copied in step one
4. Hit the
button a second time to close the tag.
5. Hit the 'Save Signature' button at the bottom of the text box.
Here is an example of what it should look like: (red FR-S example)

Scion FR-S in Hot Lava
Scion FR-S in Raven
