Hmm, couldn't you use gparted? I think almost for sure this would work for ext2/3/4, not sure about FAT32?

If gparted can't do an image (probably can't) then you could dd the image to a block device (like a USB stick), run gparted and resize, then dd it back in to an image file.

I'm assuming this won't mess up the boot pointers into the fs. Should be fine for grows. Shrinks should work if the bootable bits are at the beginning.

Or am I out to lunch here?
