Is there a way of checking if a digital image has been altered?

Not sure how sophisticated the 'suspect' is, but most of this things that crankarm posted about are easily defeated.

Indeed, there are a lot of EXIF editors around.

I think that the only guaranteed way to spot manipulation is expensive forensic software.

He should be safe Sheep don't tend to have digital cameras.

Shepherds do.

I love most early Who stuff.... wonder if their pictures were doctored ( to get back on topic) ?

Patrick: hope you don't mind: I copied your post onto a forum with a lot of expert photographers on it, but I'm afraid the answers I got were not really of any more help to you, than what you've been told here. It really is a case of 'calling in the experts' - if your client can afford it! It needs a proper forensic analysis.

True: there is an EXIF header on most unaltered digital camera photos, which gives detailed information about how and when the photo was taken, but that is easy to fake back in - a fact which your opposing counsel, if he or she is in the know (I assume these photos are concerned with some legal proceedings) will use to tear your evidence to shreds...

... literally

Are you sure?

There has been software in the past that could tell if the picture from a particular camera has been altered....the first that I came across was by Epson....Nikon have made their own too in the past but that was only for use with their then top of the range dslr.
