It would be nice if we could use the curves tool in the batch queue manager, but it not seems possible at the moment.

If you try to open the same tool in the next image, you will see that the settings are the same of the previous, so you just need to click "OK" to apply the changes. This way you just open the image, apply the changes, save and go to the next. Maybe not the fastest and most elegant way of doing, but it should work.

The curves tool seems to be the easiest way to get what I want, I can
cope with doing the images one at a time, there aren't *that* many of
them.

Thanks all.
