SSH key fingerprint is shown by running this command:

ssh-keygen -lf /etc/ssh/ssh_host_rsa_key.pub

and the fingerprint is some strange code. Is there a way to turn this code into an image hash or something like Gravatar?

Add a -v for ASCII art:

michael@challenger:~> ssh-keygen -lf /etc/ssh/ssh_host_rsa_key.pub -v
1024 8a:84:4e:34:60:9c:64:94:d0:29:0b:75:82:60:2c:89 /etc/ssh/ssh_host_rsa_key.pub (RSA)

If you want an image, I don't suppose you've tried Just Doing It with Gravatar:
