When burning a CD/DVD is it possible to "stage" it?

I need to burn a DVD (that's all I have, not CDs) with just a few MBs of pics. DVDs can store up to 47GB. Is it possible to burn the DVD today with just a few Megs and then tomorrow burn another few Meg and so on and so forth? I know that spindles of DVDs are dirt cheap but still I wouldn't like to see an entire DVD get "sealed" with only a few MEG. Also will any CD burner SW do this or is this a special feature that you need to make sure your burner supports?|||as long as they're DVD-RW, it'll be fine. if it's just DVD-R, go grab a flash drive
