It would work, you just have to use the

instead of the imageshack link of:

I use imageshack for everything. Never had any bandwidth problems.
Your models look nice and creepy. If I had to suggest anything, I would suggest breaking up the texture with a bit more variety. You've got the creepy skin tone down, and the blood, etc. how about some muscle/bone definition, etc. It sounds silly, but I'd throw a pair of pants on them, or if they are scifi, maybe torn pieces of a spacesuit.
Anyway, they look good and it seems like you are getting ZBrush down pretty well.
