So pay attention to such details in your pictures. Also deactivate the stamping of the time and date on your images to make such attacks more difficult. Stamping means that the time and date are inserted legibly in a corner of the image.
Also make sure that the date and time are not included in the metadata (Exif information) of the images or in the file name. You can use apps such as "ImagePipe" to delete metadata from your images before you publish them. If possible, deactivate the saving of Exif information in your camera settings. This information can include the date, time, smartphone model, camera type, operating system, coordinates and more and is invisibly attached directly to the images.
