These are PDF files

Can you open the file on the machine independent of LF? Say with Acrobat?

To clarify, these are PDFs that have already had their pages extracted and re-extracting them seems to make the problem go away?  The first error code is about Web Access trying to show you an image page, so it thinks they exist.  The temp file referenced in the error should be a png, can you check that it's in that location and that it is viewable as an image (if you make a copy with the png extension)?  I wonder if WA is having a problem getting the image data, and that's the underlying cause of the codec error (since it can't tell what codec to use).

Dear Brian,

Just to add onto the above, I have checked form the storage area (path) in the Disk, and seems the image is missing. How that happened, I do not know. Now I have to search for each document that is displaying this error in order to regenerate the image. In that case is there a way that I can search for these documents from the repository. Note that the "Page Count" column shows that there are pages whereas there are no pages.
