Angelina as long as the face is not visible
Another risk with pictures online, is that mobile phones typically add the GPS coordinates where the picture was taken to the picture's metadata. (Within each jpg, and many other formats, there is an EXIF block that contains all sorts of details about the camera and the settings, the date it was taken, and, if available, also the coordinates where the picture was taken.) Many picture viewers and editors can show you on a map where the picture was taken (usually with a precision of a few meters/yards) - great for vacation pics, for example, but they will also betray your location when you share a picture that was supposed to be anonymous. So if you take a nude picture without face or tattoo visible, if the location shows it is taken inside your house, it is still likely that it is a picture of you.
Some social media sites automatically remove location data when you upload, but not all. You can remove the location data from photo's with a few steps, but how differs for Windows, Android, iOS, so do a search if you want to know. You can of course also turn off GPS on your phone, and some camera apps can also be configured not to store location data.
