Batch convert CMYK to RGB

[Chris_J_W]

Hi, I've got a pile of images (~2000) to put on a website for a photo gallery from a tour. Unfortunately, majority of the photos are in CMYK format, which is useless for websites. Is there any easy way to convert all of these to RGB? Some sort of conversion program with batch processing support is what I'm after...(free would be ideal).

Thanks

Chris :D

Imagemagick - a free programmers api to this eg perlmagick but you have to do some programming. imagemagick.org - there is a windows binary available to run from the commandline. I know it supports CMYK and I think it does colour space conversion.
Photoshop can be automated to a degree with macros.
A UK company called highwater used to sell a heavyweight professional graphic convertor program

Upon closer inspection, it appears that the images are all supposedly RGB format already. There must be something else wrong...I have had limited success with opening/saving them in Gimp, then uploading again and they display fine, so my current theory is there is something about these pictures that Gimp doesn't support, and as such is removing, and that is making them work. I don't know what though. Also, the ones that don't work vs the ones that do were taken from different digital cameras (I don't know what ones though)...anyone got any ideas?

Edit: Found the problem - I'm so dumb! Somewhere between me running the script to generate the links to the files, and uploading to the server, the case of the filenames got changed. Obviously linux (where the webserver is running) is case sensitive, so differing cases breaks things. Fixed and its smooth now. Thanks for help. :o
