Yes--PDF is capable of handling linking--and there are a number of benefits to using this format, it allows you to use a wider variety of image formats without having to convert for browser compatability, it keeps the images and pages self contained (rather than a bunch series of pages and JPEGs stored in various folders), it requires no tweaking or rewriting code--and you can save it from a number of desktop publishing or word processing programs (even Illustrator files work in PDF format) and the final tutorial files will look EXACTLY how you intended them to look, regardless of platform (basically, the resulting file will look like a virtual book--rather than a webpage). Its as easy to use as printing a document (without the messy cartridges).
