LIGHT MAP DILEMA!

I have a dilema!
I would also like to get some advice as to how to create a working Light Map. I know already how to make the effect itself, but how to actually make it work is the problem. I currently am not sure on how to do it. So far, I have tried taking a screenshot of the map in x1, and then using layers in Gimp to create the effect, yet, when I import it into RM2K3, it says the image is not the right size (either it's too big or too small) ???. Does anyone know a method that works? And how would I go about doing it? Sorry if I have worded the question badly :-[.

Specify more what the effect is. What are you importing the image as? Panorama? Picture? Make sure the screenshot is in the right scale, as in, you've pressed F5 first.

Well, I am importing it as a picture. It's a light map, so basically it is lighting effects for light sources, etc, like an overlay (picture on top of the map to give an effect). I'm also not too sure on the scale of importing a picture (the maximum size for a picture). I should have mentioned that in the first post... My fault :-X.

Alright. I'll try that, and tell you if it works.
Thank you for your help :D!
