When I'm working on my maps in Paint Shop Pro 8 and viewing them in Windows Photo Viewer, I see the identical image... a nice, bold contrast of lights/darks. However, once I post them on the web (deviantART, here at the CG, etc.) and view them in Mozilla Firefox, they look significantly brighter.

Can anyone help me, please? This is driving me absolutely nuts. I'm assuming I need to tweak something in Firefox, but the few guides I've been able to find with a Google search are extremely confusing (may as well be written in Greek), and I'm not even sure if they're the solution to my problem (something about changing ICC color management...?).

TIA!
