How do I post screenshots from my switch on TBT forums and instagram?

I'm curious as to how so many people do this. What's the best way?

some people make a twitter account dedicated for animal crossing screenshots, easier that way

I post them to my Twitter account, download them (then delete them from twitter) and upload them to ImgBB to be shared elsewhere.

A more tedious way that I use is putting a MicroSD card into your switch and putting Screenshots on that and later get them off via your computer/phone.

Just an alternative method if you don't want to make a Twitter.
