From the FAQ: http://hubpages.com/faq/
"Can I have multiple HubPages accounts?
You may have more than one account, as long as they are used in the spirit of contribution to the community. Creating large numbers of accounts for solely promotional purposes may result in all of them being banned. Creating Hubs about the same or very similar subjects in different accounts is also prohibited. Creating a new account after being banned is also prohibited. Please stick to a persona in the Forums; using more the one account to post in the same Forum thread is not allowed."
I've never seen any reason to indicate you can't have the same image on two accounts, as long as you abide by the above rules.
I think I have about 6 accounts at last check.
