I honestly don't know how to put on those so-called on the images I put on pages. I just know how to put images just to make the page look good. Like most the images I put, the one of Dennis Orcollo and Lee Van Corteza come from a photo gallery from www.worldpoolchampionship.com (2004 edition). This means those pics are rather old and it's unlikely that they still have any copyright.
2004 is not rather old.  Images published in the United States before 1923 are old.  The images you uploaded are probably copyrighted.  If the website you found them on does not explicitly say that the images are released under a free license or into the public domain, you have to consider them copyrighted and unavailable for use.  You could consider emailing the photographer and asking them to release it under the GFDL, though. Take a look at this page Wikipedia:Image use policy, this page Wikipedia:Image copyright tags, and this page Wikipedia:Copyrights.  Your images will probably be deleted unless you can show they are free to use.  (Talk)
