I've been working on a small website that allows image uploading. I've uploaded a few images from other websites and noticed when images were shown within the web browser, the privacy indicator in the status bar of IE appeared. Clicking on it, it stated that a cookie was blocked that was attached to the photo and gave the domain and path the image was attempting to create a cookie for. Scripting I use is Perl. My question is: when users upload images, is there a way to "detect" if the image has any code attached to it that would create a cookie, track, or do anything other then "just show an image?" And if so, is there a way to strip it? Or have all uploads run a process of having any code stripped, regardless if any exists? Thanks-
Additionally, for users who opt to simply supply a URL to an image versus uploading, is there a way to prevent those images from executing code, track, or create and set cookies.
