Outer Limits 4x4 Board

Just been browsing the classifieds and noticed that only about 50% post up pic's of what they're selling. This is a pain especially with tyres when you want a good look at the tread. I think some need math lessons too as some of the tyres dont look like the % of tread claimed, especially when you know what they are new. I always ask for the tread depth in mm anyway.
So anyway are pic's mandatory in classifieds?

No and this is not Tech. It should have been in Chit Chat.
