Drawing and saving images in list

Here a very simple app to draw lines by finger on the first screen, save the image in a list and displaying the images on the second screen.

Is there any idea to save the images in a cloud and/or print the images?



What about uploading them to cloudinary. Then when you get the url, you could send that through a google app script to make and send a printable pdf

Thank you @jared,
I managed to upload the images to cloudinary and get a URL of the image. But I have no idea to make a google app script and run it from the app to print.
