in the app store type in " Photo editor" there you can download lots of free apps to create and modify. Then to not copyright you can go to https://pixabay.com/ to get images that are available for re-use. Or you can go to google image search then type in a search click "More tools" then select "labeled for reuse with modification". These are also images that are not copyright protected and free to use.
But make sure to edit the photos you download and not just repost or copy paste.
