Uncomplicated, unfussy, even for a newbie!
I have been using Xara Designer for nearly 30 years in its various iterations, originally as a design tool for producing website graphics. However, the software has developed to such an extent now, that I can design a complete website using the software, including navigation etc and with one mouse press, export the whole site in one go. Xara generates the style sheets, the jpegs, the pngs and the html. The clever thing though, is that you can also use the software to create pdf documents for easy print, high res photo editing and so on.
I have no axe to grind, except as a very satisfied long term user. You can try before you buy at their website.
