First what kind of camera do you have?
If there is a manual setting to the camera in other words you can set the shutter speed and apature.
Then meter off the house on the ground before you fly. Then leave the camera settings alone so that is shoots the same exposure in the air.
As for fixing it in photoshop there is 2 ways I know of the "adjust" that kind of exposure. I am sure there are more, but this is the limit of my knowledge.
1. IF the images were shot in RAW or NEF format. You can adjust the EV in the Advanced RAW features of Photoshop.
This means you would have to shoot the images in RAW format to begin with. Only the higher end digitals have that feature.
2. You can find the best compromise by adjusting the brightness and contrast of the image.
As for posting you have to either put them in your gallery or host them somewhere else on the internet and put them in your post with the IMG tag.
Hope some of that helped.
