Batch Image Manipulation software

OK i take a lot of photos, mainly at 2 or 3 Mega pixels.

i then eather arcive them or post them up on my website

the problem is if i have 50 photos and want to post them on my site i have to rsize them all down to managble size - it there some software that can do this,becasue doing them one by one it paint shop is dull

also i could do with being able to alter file name in mass ie,

DSCF0001.JPG, DSCF0002.JPG, DSCF0003.JPG, DSCF0004.JPG, etc

into

rc_01.jpg, rc_02.jpg, rc_03.jpg, rc_04.jpg, rc_05.jpg, etc

and so on






thanks daniel

Photoshop is the daddy will do this standing on its head.

yeah - also i heard (from "another place) that Jasc Image Robot is quite good

- but i cant find it on Jasc's site cos now they only do it as part of paintshop 8
