Hostmonster is loaded with stuff and thats where I host my site. I pay though and its around 100 or so a year but thats cause I have 2 url's If you want free theres a few out there but its been so long for me I have no idea. Have Deviantart Portfolio work for ya. Its free
Most of my friends just used blogspot and it's portfolio option>
-I- used Deviantart's portfolio option (which doesn't link to your main page, and therefore rids all those journals and sketches). I got two professional art jobs using it, so... I'd consider it viable. I just personally like putting more of my time into art than into building a website.
I hear from my professors that DA isn't a good portfolio website, as it is unprofessional, but is a great way to branch out. They suggest Wordpress, since its both free to practice on, and you can eventually buy the webpage. Good luck!
DA itself. However, Deviantart has a portfolio option that many of my bosses are totally cool with and recommended me to use. I go with the people who hired me over professors who may not be aware of the portfolio option.
I designed mine (samotage.net) from scratch, but that was after taking a class in web design... The plus side is I was only limited by my coding knowledge and not what templates I could find, so I built more or less exactly what I wanted.
I found a jQuery gallery that was pretty simple and easy to edit, so I did save myself that headache, lol
