Recently, I extracted from an .iso file some pictures, but I can't see them. When I try to open .jpg files with Image Viewer, it shows me this error: "Error interpreting JPEG image file (Not a JPEG file: starts with 0xda" (the expression after 0x is different from file to file)

I tried to change the file extension but no result.
Thanks for help!

Judging from the error they are not really JPEG files, open a terminal and run: "file filename.jpeg" this should identify the file type. –  João Pinto Feb 1 '11 at 19:01
    
you would have to change to the folder your files are in first, and replace "filename.jpeg" with the actual file that you are interested in - try "open terminal here" from your graphical file browser. –  ImaginaryRobots Feb 1 '11 at 19:20

run file yourfilename and see what will say –  jet Feb 1 '11 at 19:34

Please 1) Open Applications ▸ Accessories ▸ Terminal. 2) Type file, followed by a space. 3) Click and drag the picture into the terminal window. 4) Press Enter. –  ændrük Feb 1 '11 at 20:28

Judging from the error reported by the image viewer, I would say that the files are probably either corrupt or they're not really JPEG files.

What is the result of:

file the_file_name.jpg

The answer will likely be the actual type of the file.

Are the files named as filename.jpg or filename.jpeg? If the .jpg files do not open, do they if you rename/copy them to .jpeg?

Have you installed some image/photo software recently?

Sometimes your image viewer has not installed the Eye Of Gnome (EOG) plugins. Go to the Software Centre then select 'plugins for eog' and then click 'install', then it should work.
