Just about all hosts have a Copyright paragraph 
in the user agreement.

-----
Copyright or Trademark Infringement: Use of 
[insert hosts name] to send or receive any 
information which infringes the patents, 
trademarks, copyrights, trade secrets or 
proprietary rights of any other person or entity 
is prohibited. This includes, but is not limited 
to digitization of music, movies, photographs or 
other copyrighted materials or software.

Since one's website content has an automatic 
copyright (to my knowledge), collecting these to 
post on your own site is in violation of this 
user agreement.  The host does NOT want to have 
infringements hosted on their server.

Someone once copied large parts of my gaming 
website word for word, including the pictures 
(which were of my character even), and I 
contacted the host.  The host forwarded my 
complaint to the owner and I believe they would 
have taken further action, but the domain was 
ready to expire and the site went down anyway.
