    When I save images from my copy of Photoshop for distribution on the
    web in the formats JPG and GIF, do they contain any personal data in
    the image data? I also provide PSD files for many of the images I
    distribute, so will they contain information about my copy of
    Photoshop, or my OS etc?

    Thanks in advance.

    No personal information is embedded in these formats other than
    (possibly) EXIF data identifying your digital camera's make, model,
    exposure settings, and time, if (a) your camera includes this
    information and (b) you don't tell Photoshop to remove it.

    Well, he's saying that he distributes the images on the web. I
    suppose it depends on his image host, but you can usually back into
    anyone's entire uploaded image output from one image.

    Just randomly selecting this image:

    http://io-noi-aldo.sonance.net/blogpix/a_napoleon.jpg

    we can back into his index

    http://io-noi-aldo.sonance.net/blogpix/

    There was a flap in another newsgroup over this. A poster linked to
    an image hosted by PhotoBucket, and someone backed into the poster's
    entire PhotoBucket site. There were some images in there intended to
    be...ummm...private.

    That's easily fixed by a simple .htaccess change. In fact, by default,
    every Web browser I am aware of blocks viewing the contents of a
    directory unless the .htaccess file explicitly permits it. This guy has
    set up an .taccess file to allow viewing of the contents of /blogpix. I
    do the same thing I have two Web servers I use to host files for my
    Weblog (among other things) and I have explicitly permitted viewing the
    index of those directories.

    However, what I think the OP is asking is whether or not a file saved
    from Photoshop contains embedded within it information that can identify
    the person or the copy of Photoshop that created it. The answer to this
    question is "no."
    Well, that person was a dumbass. PhotoBucket,IIRC, allows tagging images
    as private...or he could always set up multiple accounts, one for public
    images and one for private.

    If you look at the 'File Info' window for the PSD, you'll see all the
    information stored with the PSD.

    Not the free version. You can with the paid Pro version.
    Usually, when something embarrassing happens, it's because the person
    didn't know "backing in" could be done. It never occurred to them
    that there was any need to take any precautions.
