If you are posting stuff online, in particular pictures, you may run into IPR (intellectual property rights) issues. This is just one of the reasons why you should consider content that is more or less free. Some great stuff is licensed under a Creative Commons license, which can give you the right to republish. Their website also contains a search engine for this type of content. Another search engine is at Yahoo. There is also a great deal of free music to be found through these links.
