Simple Image Slideshow
This demo shows how to create a simple image slideshow using either buttons or swiping images. The demo works as a carousel, i.e. when you get to the last image, clicking Next or swiping will return you to the first image.
You can set things up to just stop at the end.
Note the use of procedures to reduce repetition in the blocks
You can also set the screen background image instead of a canvas, and of course you can use image urls from an online server (e.g. google drive) to avoid having image files on the device
