I've got a flickr pro account but I dont really use it. It just seems like hard work to keep it all keyworded and put into groups etc. Plus, I cant see the photos at work. I've got a pbase account. I'm really happy with it. Its easy to get up and running with a simple nice looking gallery and when you're feeling brave you can delve into the css for some serious customisation (or use one of the provided themes). Its $23 per year for 500mb of space which I think its pretty cheap. The other great thing about it is you can upload via a zip file and it unzips it for you into your gallery which is great if you have an annoying internet provider that compresses jpgs on sight! Also, there is a nice community feel to the PAD forums if you go in for all that sort of thing.
Mine front page is customised but I havent really gotten around to finishing it and picking a style to back fit across all the older of my galleries. Here are some example of the various styles:
custom front page: http://www.pbase.com/suzy_walker/
custom gallery style with custom headers: http://www.pbase.com/suzy_walker/reefbeasties
off the peg gallery style (one of the many): http://www.pbase.com/suzy_walker/travel
using someone else's css: http://www.pbase.com/suzy_walker/macro_mystery
You can do slideshows or tree views on galleries too. I guess I'm just used to it now but I really like the navigation. A friend of mine was on Zenfolio and I really couldn't get on with that navigation.
I started using red bubble for a while too (I liked the idea of designing my own teeshirts and selling photos etc). This is free and there's a nice community feel here too but the prices (to sell and buy art at) are not in your favour if you are based in the UK. They do allow you to create a nice website as well as your profile which is a nice feature.
mine is here but I dont check it too often :
profile: http://www.redbubble.com/people/muzy
bubblesite: http://muzy.redbubble.com/
I'm going to try photobox next, when you sign up they give you free prints but I havent ordered mine yet. I dont think much of the layout so far though.
I used to host my own website but not many people came to see it (its difficult to get a large google rating if you don't have loads of links to you). I might go back to that one day but I like the community feel too much, lots of people get to see and comment on your images and its really interesting to hear what people think (good and bad).
I dont know if thats useful to you at all?
