Attila: Picasa (the photo-sharing site from Google/Gmail) uploads RAW images, and does a decent job of it. (we shoot with a Nikon D70 or D300) For 'true' photo processing, we've become a fan of "Adobe Lightroom." (Adobe apparently interviewed/worked with photographers to look at their work-flow in Photoshop, and created this version) It's a memory hog, but you can get brilliant results.
For Picasa, you need to have a gmail account - but it's free. (I can't remember if you still need an 'invitation,' but - if so - PM me, and I'll send you one) You never need to use the email program, if you don't want to (although I love it), but Picasa would be worth it. You can choose some albums for public viewing, and some that require an 'invitation' (ie, I have friends who keep any photos of their children in private albums to send to family members/friends, only). And there are basic editing tools - cropping, some contrast adjustment, fill-light, red-eye, etc...
