I need help in validating uploaded file whether they are one of these image .jpeg, .jpg, .png. After researching I found that these methods are useless like exif_image, finfo, getimagesize they can be by-passed by using/adding some magic numbers in files and can be spoofed. Is there any full proof way to do this?
