A lot of folks accepting image uploads don't realize they need to remove the exif data from the images, as that often leaks gps coordinates if they were taken using a cell phone. With imagemagick, you can use the `-strip` flag[0] when processing the images to remove that info.
It's shame all exif info is stripped. I like to see the camera info, such as focal length, aperture and what lens too for interchangeable lens cameras.
A responsible site will strip this on the user’s behalf, but no one should rely on that.
If I want to be lazy about it and quality doesn’t matter, I’ll take a screenshot as a quick way to strip EXIF data, the location being the key piece I want gone.
I don't grant my camera app location permissions, so the images are never tagged with gps in the first place, but I also will screen shot pictures before sending them anywhere.
IIRC This is how John McAfee's location was leaked when he was on the run, a Vice reporter took a selfie with him and uploaded it to the website without stripping the EXIF data
