It's a photoshop 6 action.

Pekka,

Tried this out per your advice in another thread. It works well, but I wondered if you have a specific reason why you use the sRGB colour space instead of Adobe?

Regards,

Roger

The sRGB color space applying in the end of the action is for www export only - you can take it off if you don't need that.

Fred Miranda was nice enought to put the action there for download, too:
