PI96596: IMAGE GALLERY EXTENSION SETS THE WRONG CONTENT-TYPE HEADER FOR NON-PNG IMAGES

APAR status

  • Closed as fixed if next.

Error description

  • A Cognos administrator uploads an image gallery extension, like
    the sample "SampleCustomMediaAll.zip".  If the gallery contains
    non-PNG images (for example, JPG images), when a user opens the
    image gallery, the server sends the images with an HTTP header
    of Content-Type: image/png.  In most scenarios this works fine,
    but if the web server is setting the security header
    Content-Type-Options: nosniff then Internet Explorer will fail
    to display the images when it tries to decode them as PNG.
    

Local fix

  • Disable the Content-Type-Options header in the web server for
    requests which load the image gallery files.
