website builder/manager software

I made myself a little site a while ago, and while it doesn't look to bad, it's proving a pain in the arse to add and manage content, so most of my pics remain local to me

I could make a simpler looking site, or use more complex code, but that isn't my style

my site - http://homepages.nildram.co.uk/~tux/

Anyone know of a freeware app that'll at least help me?

An app that would allow me to drop the raw files from my camera, and have it output the 800x600 and thumbnail images would be an awesome help


BTW, i made my site with mozilla, photoshop elements (no batch processes afik) and smultron


Thanks
