File size depends upon the file type and bit depth and compression. The bit-map size for a 6MP image at 8 bits per pixel is 18M bytes so consider that size the worst case. There are no universal parameters so take the following as a rough guide only. Most good digital cameras offer several output formats, RAW which would be around 12MB (and allows access to the full colour depth of the image), TIFF which may or may not be compressed and JPEG at several compression rates. Most digital SLR cameras provide TIFF and JPEG images at 8 bits per pixel, a compressed JPEG image may be from 4.5 to 2.5MB in file size. You might learn a little if you check out the specifications for the D60 or similar cameras.
