i was actually just thinking about this recently after reading palandus's response... while royalty free images would be perfectly fine, there is a lot to be said about the theatre of the mind... if that is what is kept, then the focus should be more with the intent of this being essentially an interactive book, meaning all focus is on the writing and I would say the UI needs to be made better with more options for font size and maybe a small handful of color options to make sure no one has trouble reading stuff... which I know from the roadmap UI is already a work in progress so... will just have to wait and see about that
