australians likely to smoke 10 joints, a week, page-9

Sorry, I don't really get that:

Most links(pictures etc.) he inserts perfectly, but some aren't allowed, because of "external".
I don't can really see whats special on these (external)links.
I'd post it again, but probably same again.
So, may that works -it was on *, should be 1st link:
https://www.google.com/search?ei=JI.......0...1.2.64.psy-ab..1.0.0....0.5IBo13bxNIE

I actually also wanted to put a nice picture in -the (eye)glasses woman.


May can anybody explain: Why, and which, links aren't allowed(as "external"(and Why?)), and which are??
No idea, sorry.
