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.
