Your web site is listed in your profile page. To add links to a web page in either a post or in your sig, you need to use the "UBB Code" syntax described here . For example, the link at the bottom of my sig was created by typing the following without the spaces:

[ url=http://www.prillaman.net/prillaman_master_show/ ]some art[ /url ]

That creates some art .

Likewise, you could put the following in your sig to link to your shutterfly page:
[ url=http://www.videodrome.shutterfly.com/ ]my web page[ /url ]
Take out the spaces and you get my web page
