Nice tips. Being a researcher myself, I have been to many conferences, and I have noticed that a lot of researchers are poor presenters. They go too much in depth, not taking into account the fact that most people are not really interested in that, but are more interested in things which they can understand. So, the basic aim of your presentation should be to attract the crowd to read more about your work later on. Therefore, you should touch only the main points of your work in your presentation, which are easily understandable. Like you mentioned, using more images is very helpful in this regard.
