I was just browsing and am always interested in Wordpress books. I saved this book on my wish list, but after reading about how small the pictures are, etc., I will have to take it off now.
Before browsing here, my intention was and still is to watch video training on WordPress at Lynda.com. I have never tried it before, but the paid library is immense with every topic on software training imaginable. Just do a search on the site of what ever topic you like!
I've watched other training videos on WordPress before and have purchased some books on it, but I find it easier to watch a video. I don't have any affiliation with Lynda.com, but just wanted to pass on what I found out.
