bic on "Google Analytics"

Hi all, I've been away for a while but of course I'm still using Zenphoto and customizing it for my needs sometimes.
Recently I've added google analytics to my theme. I noticed that an old third party plugin is no longer maintained nor hosted by the original creators. Since it's quite easy to make a new plugin for this purpose, I was wandering if you are interested in it. If so, I can provide it quite soon. My only concern is that at the moment I didn't find an easy way to place analytics code just before the closing </head> tag, as recommended in google guidelines for analytics, since theme_head filter is not placed there in all themes. I don't know exactly if this can be a major problem. BTW, of course in my theme I have placed the code where google asks it to be.
