Please Help!

hi, I have just recently downloaded adobe Photoshop elements 15 and premiere elements 15. I am new at this and don't have a lot of experience but I decided to take on a large task, to make a stop motion. I had many edits to do on many on the photos so I used photoshop. here is my problem when I go into the video editor to create the "film", under add media, there are only the photos that did not need photoshop. this ruins my "movie". I do not know what to do. what may help is if I knew how to get photos from photoshop into organizer so I could put them in video editor. I have another question too. how do you make changes in video editor that change all of the frames?
