Always, that's illegal, is "bandwidth theft" someone else is paying for you to post their picture on another site:
http://altlab.com/hotlinking.html
Froggie, get a free photo site of your own
http://www.emailaddresses.com/online-photo-album.htm and upload it from your computer to there and use that address or get a free blog, here from PC or somewhere like Google's
http://www.blogspot.com (where I have mine) and upload it there and then use that address. Basically you just need your own site of some sort and the site will have instructions to how to upload pictures and things and how much space you have to do that, etc. Then you can use the URL of the picture to show the picture here.
