Yes.  The one above is an image of a floppy disk (fda).
If you have the floppy version of BL3, you already have
a bootable image:
-------------------
qemu -fda disk1.img
-------------------
That will boot the first BL3 floppy.  Press CTRL-C when
it asks for the second floppy.  Or you can make an image
of the second BL3 floppy and use that when it asks for
the second floppy.

Alternatively (and simpler), you could download the complete
BL3 image that James did.  It is listed at the bottom of the
BL3 homepage.  You boot it (after unzipping) without the -fda
parameter.

If you decide to use two floppy images, let me know and I 
will tell you how to get the second floppy inserted.  It's 
not immediately obvious.

dd if=/dev/fd0  of=wombat

That puts the image of the floppy in drive A: 
into a file called wombat

Yes.  After qemu boots the image file, it treats it like a normal
drive.  You can save, delete, format, whatever.  You can even use
fdisk to put partitions on the image file.  

Cheers,
