if you take your pics from the mirror, and the flash spot is coming from the reflection, then you may want to set your camera on a dresser or something and turn on the self timer to eliminate that altogether. this is what I always do.
I turn off the flash and take the pics in a well lit room. Like others have said, if they come out dark, I just brighten them with Picture It or some other photo editing software.
Looks like its all been said! Make sure to turn off the flash, and stand in a very brightly lit area. Usually bathrooms tend to be well lit, as the light around the sink adds additional brightness. Good luck!
I have the same problem with my pix and I can't figure out how to work this camera. I'm going to have to start using the electrical tape. But not till hide your hair is over
