Hi there I just bought a eos d2000 camera and am concerned about the file size when transfering the images onto my laptop. they seem to be way smaller than most digital images and im not shure if this is a problem with the camera firm ware.

Go into the camera's settings and see if there is an option there to change the resolution, if it's the size in MegaPixels you're concerned about.
There may also be an option to take the pictures in RAW format rather than JPG, if it's the size in MegaBytes that you're concerned about.

Other tell-tale signs of small files could be:
File is a video file.
Picture was taken as a burst or panoramic.
Digital zoom was at full. (Try setting the camera to not use digital zoom - it's basically just cropped.)
