If you want to use a picture in a blog or forum post, feel free to hotlink to the image on my site. If your site lets you post HTML:
<a href="http://www.wireheadarts.com/photo/astrophotography/eclipse2008_1/"><img src="http://www.wireheadarts.com/photo/astrophotography/eclipse2008_1/view.jpg"></a>
If your site uses "Forumcode" or "BBCode" this may work instead:
[url=http://www.wireheadarts.com/photo/astrophotography/eclipse2008_1/][img]http://www.wireheadarts.com/photo/astrophotography/eclipse2008_1/view.jpg[/img][/url]
