In Berne convention countries (most of the western world) every work
is copyrighted by the creator upon the moment of creation. Federal
Law requires you to get permissions from the creators unless you're
intending to never show the collages to anyone, never put them on the
web, never print them out, never frame them, never publically use
them in any way.
Fair use only applies in very limited ways mostly in educational
settings and then only for single copies and only when there's no
money being made from the infringment.
My suggestion is to create your collages from material on RF discs,
where you pay a one time fee for any usage of anything. Otherwise if
the work you use has a registered copyright you could be liable for a
fine up to $150,000 and the legal fees of the holder of the
registration.
As a creater of copyrighted works you can help yourself to those same
protections by the simple and inexpensive process of registering your
own works.
