How can I optimize the image ?

It seems like the orginial image built from Denzil & the newest version of meta-esdc2012 gets a high size (sato >500mb). I have already got demo packages. Demo SATO got only ~170mb but it worked very well. Maybe this relates to the BSP guide but it has a little information for a newbie to understand overall how to do it perfectly.
