Adding pictures from google picasa
From Walfriedswiki
The easiest way for including "Picasa" pictures in "walfried.nl" (i.e. the drupal website) is via "Iframes".
<div class="field_myiframe"> <iframe src="http://picasaweb.google.com/walfried.veldman/Bettmeralp2007#slideshow" width="500" height="400"> </iframe> </div>
you can also provide an ordinary link:
<a href="http://picasaweb.google.com/walfried.veldman/Bettmeralp2007#slideshow">Bettmeralp</a>
