Does anyone know of any good photo gallery scripts? It must be SEO friendly, for example if i make a category for "dogs" when i browse the site it should use the keyword dog in the URL. Must also use mod rewrite for static URL. Adsense ready would be good and it must be able to cope with around 400 - 500 categories. Bulk upload feature is a must. I know there is a lot of FREE scripts out there, but i don't mind paying for a commercial script if its good. Can anyone point me in the right direction?
