NEED A POWERPOINT TURNED IN TO SOMETHING ACTIVE AND NOT STATIC

For our non-profit's holiday card this year we have compiled quotes and images and would like them turned into a little film or .giph or something that moves. I don't think it's super complicated but I sure don't know how to do it! LOL
It is currently in powerpoint and essentially I'd just like each slide to transition inlet in a loop with enough time for people to read the quote but not have to do anything but watch. I have attached a powerpoint but there will be one more slide added to it to be complete.
Creative ideas are very welcome.
Please send a sense of your idea on how to bring this to life -- "I'll do it" isn't going to get a reply. thank you!!
