Exif data can contain everything from the make/model of device used to take a picture, to a gps location of where the picture was taken.
Removing that information depends on what you're using to do it, but can be done with an exif editing tool in pretty much any OS I'm aware of.
Edit: Autocorrect is a pita.
I'm in hard agreement with you, EuroTrip Yoda (had to).
My in-laws definitely voted Harris, my dad passed 4 years ago (Vietnam vet - not a trump fan), and my mom went down an idiotic rabbit hole. I haven't talked to my mom in weeks, and I'm sure she knows why.
She also doesn't know that we are planning to leave the country. I can't stay in a place that will reduce my daughter to a second class citizen without bodily autonomy. Yet that's what the nitwit I called "Mom" voted for.
