If you have a copy of a document, photo, or other item, you can usually use that copy in court just like you would use the original. Courts treat good-quality copies the same as originals in most situations.
There are two exceptions. First, if someone seriously questions whether the original is real or was tampered with, the copy may not be accepted. Second, if something about the situation makes it unfair to use the copy instead of the original, the judge can reject it. Outside of these two situations, a copy works just as well as the original in court.
