LIGHTING EFFECTS, RM2K3

Here is my article, I ended up doing a lighting tutorial earlier than I thought.
Please comment in the article if you found it useful, it'd help me in turn, thanks.

I know this is old, but I can't seem to figure out how to get the picture size match the screenshot of the map. I made the circle and stuff, but the image/circle won't line up with the map where I want it to (Like on a lantern). :/

+*EDIT*+
Ok, I got it to line up, but now when I enter another room/map and then go back, the light image gets displaced. It depends on where the player is spawned or transported.
Could there be a way to fix this?
