What phone are you using? On Samsung you just open the picture in the native Gallery app, tap the three dots menu in the corner and choose Set Wallpaper.

If you're not using Samsung then I would expect that brands picture browser to have a similar feature.

Or the other trick of constantly prompting "Turn on / Maybe Later" until people either accidentally accept or just give up to make nagging stop.

When searching for a pick, there were many with Micro USB ports, but only a few with USB-C so chose based on that. In the app, you choose what ear your working on, but found my brain needed the opposite view.

After initially pulling out chunks of wax, sometimes I feel blocked but can see it's my ear canal being irritated, and with it clear, can use olive oil drops or moisturiser on a cotton tip to treat the sore areas.

As someone with waxy ears, an ear pick with a wifi camera built in. Would get blockages, cotton buds just pushed it back, olive oil or peroxide would get air locked. The webcam ear pick was super cheap and makes it easy to scoop out any lumps of wax.

I tried many from Amazon, best was one called Airmax, but irritated with regular usage. I've since found "Noson.ch" and their design is fantastic. You have to buy direct from Switzerland and it's expensive, but personally it's worth it for a better nights sleep.
