Dreamweaver - Creating a Gallery

I've used Dreamweaver in the past to build a website and been pretty much successful, but having to use a much more updated version on macs, getting used to the basic layout, even following a tutorial on paper and through verbal instructions... I still got lost when it came to creating a gallery with primary images. I managed to follow most of what was said and did eventually manage to get back up to scratch and save what was covered in the tutorial to pick up next time.
