Lulu is my favourite for text-driven books, but if you are more interested in picture-driven publications then is the one to choose. It is easy to use – if you stick to the easy templates – and you can easily import photos directly from Flickr other photo sites. The standard of reproduction is impressive (as long as the original resolution is good) and they helpfully flag up photos that they don't think make the grade in terms of quality. Lulu and Blurb aren't the only fruit and, if you have time, it is worth trawling through some of the dozens if not hundreds of minnows that keep popping up – while being on guard lest they are trying to take a quick buck from you. There are various lists of top 10s on the web, or just try your luck with something like Fastpencil which looks easy to use though I haven't followed it through to publication or CompletelyNovel which is based in the UK.
