You could also obtain a replica / dummy / display model of your required phone or similar for 10 bucks or so and explode itt ?

Alternatively, find videos on youtube of people blowing things up for fun. I feel like there has got to be a channel like that.
I used to get my images from Youtube/ poorly-rated Amazon reviews all the time - photoshopping a piece of paper or whatever was needed for the SE.

Personally I'm skeptical about others having used the same images for an SE / the rep having seen them before. It's not hard to find such stuff with a simple Google search. For example that monitor, whilst searching for an image of one on fire, I found s pretty adequate image, however it was so easy to find online, it kept popping up when I used a wide variety of keywords in my searches. No imagine the rep done the same just to check (who knows, maybe they love their 10 an hour job that much). It would have failed there and then instantly.

So, I don't mind spending a tenner or something to have unique proof of destruction or whatever else, gives a much higher chance of success
