    Wow.  What is the history of this image?  It looks like more than just JPEG artifacts to me; it looks like someone used an "artistic" filter like oil painting or something.  Regardless, I'm not sure that you can do much about it.  Can this be re-scanned?

    AntionioP is, of course, spot on about the image. These are not artifacts caused by JPEG compression - an artistic filter (smudgestick or sponge or watercolor etc) has been applied.

    - Now coming to JPEG artifacts, please keep in mind that JPEG is lossy compression.
    - So the lost pixels from the original image cannot be recovered to get back 100% of the original detail in photos especially if facial features have been lost.
    - In the case of minor artifacts though, you can do the following to get a reasonably good picture without any visible artifacts.
    - First apply the Gaussian Blur tool (Filter > Blur > Gaussian Blur) with a Radius setting of 1.0 (default) or 1.2. Click (select) the Preview option box to see the effect.
    - You can experiment with the slider to see the best setting (it will usually be between 1.0 and 1.5 - not higher)
    - Once the artifacts have been removed (blurred actually) use the Sharpen tool (Filter > Sharpen > Sharpen) or if you would like more control use the Unsharp Mask (Filter > Sharpen > Unsharp Mask).
    - Of course, your final result will depend on how good (or bad!) an image you started out with.
    - To get the best results, BEFORE you begin, first resize your image to at least double the size and increase the resolution to at least 300 dpi.
    - Resize the image and reduce the resolution back to the original after you have completed all adjustments.
    - This procedure can be used to almost completely eliminate the print artifacts that usually appear on images that are scanned from printed pages of books, magazines etc.
    Good luck!

    I'd say Paint Daubs or Glass.  There's no JPG artifacts in the image.

    Someone doesn't want the people in this photo to recognized, it has most definately been altered and I agree with Lobo, im thinking Paint Daubs or Glass, but not on Adobe scale, maybe a program packaged with a scanner or camera using their after effects program utility!

         I have worked on similar pics, sometimes I have to guess, where to put colors. Sometimes the results leave alot to be desired. All I do is 8 by 10 color. I thought a jpeg correction would help. But as I said, I cant find the tutorials. I have also asked to have the sender rescan the pic.
      If there is hope for this pic, please let me know.
          Thanks for your help,

     I had a pic just as bad, that I got out of my mothers pic album. I scaned it in as psd and still looked this bad. But it was a pic of my mother and I had a good idea of what she looked like at that time. It turned out acceptable.
       I guess it doesn't matter how the pic got the way it is. I do know that, my mothers pic was scanned the same way as I scan all pics.

    I am surprised that nobody knows where those jpeg tutorials for photoshop are. Even if they don't help on this pic, I would burn them to cd.
