Thumbs and Images not showing up but open when clicked on (or right-click view image)

I have just created a new installation of Gallery 2.2.4 into an addon domain in my hosting account using Fantasico de lux. The install went fine and I can upload images but when I view the gallery i get no thumbnails or images showing unless i specificallyy right click on them and view image, at which point they are fine. I cannot see any reason why it does not work. I have not modified anything at all. It's just a basic install which has worked plenty of time before. The site is at http://www.alexbody.com/gallery.

Any help is greatfully received!

Gallery version (not just "2"): 2.2.4
PHP version (e.g. 5.1.6): 5.2.5
PHPInfo Link (see FAQ): http://www.alexbody.com/gallery/phpinfo.php
Webserver (e.g. Apache 1.3.33): Apache 1.3.41
Database (e.g. MySql 5.0.32): MySQL 5.0.45-community
Activated toolkits (e.g. NetPbm, GD): defaults
Operating system (e.g. Linux): Linux
Browser (e.g. Firefox 2.0): Firefox 2.0.0.14 & IE 6

OK. Finally worked it out. The URl Rewrite plugin needs to be deactivated and uninstalled and then it works. Not sure why but it does!
