How can I increase the brightness of photos on the HTC Wildfire S?

I just moved from a Sony Ericsson C510 to a HTC Wildfire S. Although the Wildfire as a flash and the C510 doesn't, I was able to take pictures in dim rooms better with the C510 than the Wildfire. **Even using the flash creates dark pictures.** For example, in this picture you can see in the reflection in the picture glass in the lower left that I used the flash but **the flash was so weak** that it didn't seem to make the picture any brighter than without the flash.  **What settings can I change on my HTC Wildfire S to help make pictures taken in dim rooms brighter?**
