This image is only 8MB,why it requires 32MB Flash since basically Flash is used to store IOS image?
Is it true that generally I can copy an image to a Flash a little bit larger than the image?As long as I can copy it to flash,I can run it,right?

In flash requirement,I never see sizes like 24MB.Is it because the Flash requirement only has 8,16,32 and so on and those irregular sizes are not considered but I can still run a image smaller than my Flash.For example,run this image with 8MB+4MB SIMM Flash.

Thanks.
