Question mark (missing link?) home page

[tonystroney]

I have a 'question mark' image showing beneath the 'home' link on my home page which keeps its position just beneath 'home' when I re-position headers. When I mouse over it it links to my home page. Strangely, it only shows on smart phone browsers and not on firefox or IE

I'm guessing it represents a missing image link to 'home' but I can't locate what it should be or where it is.

I'd like to remove it but have limited knowledge so would appreciate some directions

I've attached a screenshot from my Sony Ericsson Xperia ray, O2 network

Many thanks
