Photoreading will help make the learning process easier. For being able to memorise 1500 graphics you'll want to us memory techniques as well. Photoreading isn't about instant recall of picture perfect images or sentences from a book. It is about learning/understanding with more of your mind.
To what extent photoreading can help you is up to you. When you use more of your mind for learning you have better retention and recall on the material that you have applied it on.
If you are considering purchasing the photoreading course consider also the other areas of your life where you might apply it.
If you want to develop a better memory I recommend the Memory Optimizer course. It is more than just about memorising stuff that you are learning. It's about developing a better memory as a whole. If I were to learn kanji I would personally be using more of the techniques from that course than the photoreading one.
