Proving a photo was taken/uploaded on a certain date
I am in a legal case and need to be able to prove that a photo that I took on a certain date really was taken (and uploaded to flickr) on that date. Unfortunately, it appears that the "Taken on" date can be edited, so that the other side in this case can say, "Well, maybe you edited the 'Taken on' date." It also appears that perhaps the EXIF info could be edited as well. While I have not edited any of this information the mere fact that it *could* be edited could potentially weaken my case. Given that, is there a way that flickr could possibly provide a letter certifying that their records show that the photo was indeed taken on the date in question?
