... I downloaded Lightroom a few weeks ago. Looks pretty simple and easy to use. You can alter, resize etc. a lot of images in a automated batch mode. Haven't looked heavy into it...
Photoshop is great but "little bit more expensive" than Lightroom ;-)
For resizing pics for my website I use free
irfanview. I'll creat afterwards a flash gallery with
jAlbum, also free.
I have to say that I haven't categorised my pics yet. Should probably do so...
Greetings
