Red, sure, change your pic whenever you want. That's why people's votes can be modified. For example if someone adds a new spoiler to their car and it looks awesome, people can change their old vote from a 7 to an 8.
I just added the 6-10 (only 9 now, but 10 max) as normal text below the top 5 on the side navigation. Do you guys think that's a good idea, or what? When I get home, I can make images for 6-10 also if you think that'd look better. Basically, how do you think the right sidebar should look?
