You not only can add images, but also sounds as well. You can also upload a GED file automatically so that anyone viewing your page can download it and use it with their own software.
Generating the pages is very easy if you have already linked your preferred images to individuals and events and identified the clip art that you want to use on the pages. UFT gives you default clip art that you see on many of the pages listed on the UFT site, but you can add your own if you see fit.
I have used a lot of my own files on my family page which might give you some ideas. However, its best to experiment on your own until you find something that you like.
