  1. I am not able to open some jpeg files. In windows i get the
    message " preview not available" or somet hing like that. I dont
    have the message with me right now.

    In adobe photshop i get some thing like "Could not open the
    document because a JPEG marker segment length is too short (the file
    may be truncated or incomplete)". ...

    some point on my computers..

    Please advise....

  3. Are you changing the format of the file at all? Example form tiff to jpeg? I had problem with it because of this. When I changed it from a tiff to a jpeg, my computer was leaving the file extension of the previous file type in the name. But, I didn't know that, because xp hides that extension in the name. If you go to windows explorer, to tools, to folder options, to view, uncheck the "Hide extensions for known file types" box. Then when you are in photoshop, you can see the extension in the file name. Example 012.jpeg. When you change the file type, see if the extension name changes. It is supossed to. Mine was not, causing a file to be named a tiff, but recorded as a jpeg. Photoshop would not open these files. There are two options then. You can do a "open as" and open the file as a jpeg, or when you save it, you can manually change the extension in the file name. I did not like this answer, so I called adobe. After being on the phone with them for 2 hours, they basically said there was nothing they could do for me, and it was a glitch I had to live with. But, after 2 days, it just started working properly. I don't know what happened! I guess I am thankful. I heard someone else say that there is something in the proferences in photoshop cs that can help too, but I am not familiar with that. Hope this helps!
     
  4. Yeah, make sure your image has the right file extension. Check to see it is .jpg.

    Also, not all software reads all jpgs. Their are different versions. As a safety precaution always "save for web" and you will get the most readily available version. With old jpg files you might need to use something like PS or PS Elements to open them. Then you can "save for web". Quite a few programs, including this site, will not open certain jpg files.

    Again, the cure is simple. Open in PS or PS Elements and then chose "save for web". Now almost all programs will open them.
     
  5. I got a lot ofthese with a Lexar 80X 2GB card and 1DMKII recently - Lexar promised a new card within a day or two - that was over a week ago. Which card and camera are you using ?
