How can it be hooked in the wrong direction, it's the front sprocket that pulls the chain, rather than the chain pulling the sprocket?

It looks to me like the hook tips are pointing forward, the normal wear pattern for a front sprocket.

Really?
Well I've learned something new today, although I've not really put too much thought into it before to be honest. I just see hooks and presume it's fooked.  :lol

Correct that the front sprocket is pulling the chain,the sprocket rotates in an anticlockwise direction to drive the bike forwards, therfore wear on the sprocket will be on the right hand side of each U or trough  of the sprocket......so if the hooking is on the right hand side of the U....... as per pic and hooks are pointing towards direction of travel (anticlockwise) as per pic.......then that sprocket is knackered and a new set n chain is definitely needed!!!!
