Yes. If you want to update an already existing image, run this as root:

update-initramfs -k all -u

To create new initrd images, use -c instead of -u. The -u switch tells it to 
update. The -c switch tells it to create a new image. The "-k all" tells it 
to create new initrd images for all installed kernels. You can pass a 
specific version to the -k switch, but I find "all" to be easier. It saves 
typing and makes sure all installed kernels have initrd images.
