  • Hidden info in picture?

    I'd like to know if anyone is familiar with the following and knows what it depends on:

    I saved a picture to my desktop (I'm using a Mac with OSX). When I open it to view it in either the Preview program or iPhoto the picture looks the same as it did on the website I took it from.
    But.
    When I open up the desktop folder, mark the picture and get a preview of it I can all of a sudden see much more of it, just as if the picture had been cropped and I'm now seeing the original.

    Anyone that knows what's going on and if there's any way to see the whole picture outside of preview mode?

    Strange. Can you upload the picture?

        Thanx Gnep! I owe you one.

        So it's a photoshop bug that's the reason...

            BTW, question #2:

            Since the information about the original picture is embedded in the shape of a thumbnail (in the cases where the Photoshop bug has struck), is there any way to restore/rebuild a picture to its original using a thumbnail? I'm thinking something like this: One piece thumbnail, one piece genius computer program = presto, picture in original size. ???

              The thumbnail is of much lower resolution (thus detail) than the real pic. A computer cannot produce information (resolution) where there is none - it can just guess (which is what it does when you magnify a picture). You could blow up the thumbnail to where the part overlapping the high-resolution image has the original picture's dimensions, but it would look horrible. You could paste the hi-res part onto the blown-up image. This way you could give the hi-res image back its context, but it will look quite bad.
