Don't feel sad you've given it your best shot - if it is a "vbullien" issue then well let's just keep positive maybe someone can still come forward if they've had the same issue I really don't know ........ The most I've ever done is customise the colours on my Profile Page here at PC, I've never been as adventurous as you and tried to insert the picture

Looks cool though

Might I ask why you don't just use Chrome then if that seems to be working?
(says my non tech savvy who actually got lost on this thread ages ago - I'm just curious?)
