Questions about Pictures in making Portrait.......

I have a question:

Where can I get High resolution pictures so I can create a portrait. Just like the High Resolution Picture that I saw in the Portrait Tutorials and other Tutorial..

Can Anyone give me the link were can I get High resolution pictures (Players Portrait)......

That's only my problem, I already knew on creating portraits because of Big-JD's portrait tutorial....

Thank you for answering my question...

Thanks a lot......

Usually you just have to search for them using google image or similar like getty images or http://www.jamd.com/search?text=lebron% ... 20portrait to get a picture like this one http://cache.gettyimages.com/xc/7536750 ... 5C13A290DC or even viewimages.com
