MD5 for image

Hi Michelangelo,
wouldn’t be useful to have a MD5 of volumio’s image file?
I tried the christmas’s 1.1 for raspberry pi and got a sdb: unknown partition table
maybe it was no corrupted file, but a MD5 signature to compare to would have left no doubt

EDIT: nevermind, I was putting the zip file instead of the img on the SD card. Please don’t comment such a dumbness…
