thanks Mike, just did'nt give a thought on zipping up resolutions of the same dream (so large) 
though I have done this with a small file size.
Keep in mind that some people are on a download limit due to ISP restrictions and others are on slow dsl and dialup. I would keep this in mind if you really want to share your work with everyone.
that's why most of us try keeping our dreams small in size, also at the same time without compromising on quality
