Is there any mistake in the html of this page,
photo is not centered, is possible to fix it?

thanks!

I'm not sure what you mean, it's centered for me.

Oh I see, the url caused the problem. I have made it clickable so it is now able to wrap.

thanks adam,
but ... how I can made clickable URLS?

Just use noremal HTML, some tags, including the A tag works.

So in your case it would have been

<a href=http://www.trekearth.com/gallery/South_America/Bolivia/photo15321.htm>Island of the Moon</a>

thanks
