Hi. Telling you straight up. I'm a beginner. So thanks in advance for all knowledge you pass on.

Situation:
I have a 20 slide deck. I have to manually insert an image as the background on each slide... So... Background Styles, Format background, insert picture or texture fill radio button, 'Insert' button as picture choice, select image in finder window, then Insert.

Repeat for each slide because each slide gets a different background.

1st Ask: is it possible to automate this? All the images are in the same folder, image-1.png, image-2.png etc.

2nd Ask: if it is possible, what's the fastest/best way to repeat the process is the image.png files have been updated.

Any help is greatly appreciated!

Thanks!
