My lack of professionalism is showing, because I googled the higher rez picture to do the xmas'ing, xmas'ed it at higher resolution and then resized it to avatar size, but of course at no point did I save the photoshop project that would have allowed me to give you in 10 seconds what you just asked for... That said, doing the photo chop-chop knowing it will be shrinked to a tiny size allows to work like a drunk butcher, so it did not look so hot at full rez.
The whole thing being for me an excuse to do little Photoshop projects, I have no problem (re)doing the high(er) rez version, but there are still 4 or 5 avatars that have not been provided and the unwritten rule has been "first asked first served except when not"!
