No it is NOT on the web, it is a picture of ME wearing my gun in MY Alien Gear holster.
That does make it a little harder. Assuming it's a digital picture and not printed on paper...
Connect camera to pc and transfer the pic to your photo album
Go to the web and find a picture sharing site such as tumblr.com, photobucket.com or similar.
Save the pic to the sharing site and note what the filename is
From there it's just using the tag to post online.
My fave for pics that I'm going to show one-by-one ("Hey, lookie at this new toy I got") is photobucket, but to share an album of collected photos ("Hey, lookie at all these neat toys I have" is tumblr.com
