Get a non-creepy wallpaper you wouldn’t be embarrassed to show co-workers.

As I always say, as long as the wallpaper is family-friendly and not promoting anything bad like terrorism or racism, someone being not ok with it is solely their problem. People should pay attention on more important things instead of microbullying and judging meaningless stuff. You may want to temporarily adapt to a person that’s important to you in case you’re afraid of them being not ok with it or something like that but there’s no point in doing this with coworkers. It’s just ridiculous.

I wouldn’t consider an image depicting a fetish of some sort “family friendly”.

Same rules for being in public: you shouldn’t think it’s okay to subject non-willing participants into your sexual proclivities.

Is blue hair a fetish now?
