Oh well, then it would be a question of copyright (which is probably even stricter in the US, don't know about Canada).
Anyway, it's not quite the FBI which would come for you. 1st you'd probably get an "Abmahnung" (~dissuasion) by some dubious "Abmahn"-club, which you would have to pay for nevertheless. If you don't pay & don't remove the pic you may get into more serious legal trouble, but that would take a long time & since your whole homepage would have been removed by then, the judge most probably would stop proceedings & tell you: "Baaad boy! Don't do it again!"
