Problems with lighting

This is not cool at all. I don't know if this is normal, or something wrong with PS. (I have PS6 if that matters any). Whenever I make an image, and save it as a jpg, it turns out REALLY darker. It's with every image I make. It does it with gifs as well. I hate it when I made something that looks really good, save as jpg, and then look at it only to see thats it dark as hell and looking pretty bad. How can I counter/fix this?

I think pank found the cure for this... You just change your color profile to "None" and it should clear up the problem. I think it trys to format your jpeg to a different color pallette when you use save for web or something. Anyway, that should fix it.

Thanks alot man! Much appreciated!
