If you go to the Edit picture section of Photobucket you can select resize and then change the number shown in Hgt or Width to be about half of what it is...for photobucket if you change one number it will automatically change the other as appropriate.
second: You can pick up a small clamp lamp at Home Depot with a swivel neck for about 19 dollars (I got one the other day) and it clips onto the side of your desk. using the soft white light bulb shine it on your minis and take the picture with your camera in between the light source and the mini's (it should be less harse then the flash)
might be a little cheaper then a new camera
