Maximum Registry entry

Specify the maximum size of media that users are able to access in Vitalware. Size is either file size in kilobytes or, for images, width and height in pixels.

Note: This Registry entry replaces the Maximum Viewer Registry entry.

The Maximum Registry entry is used to restrict access to media above a specified size. Separate entries are available to control:

  • images
  • audio
  • video
  • documents

The Maximum Registry entry differs from the Images|Default Registry entry in several important ways:

  • The Maximum Registry entry sets a size limit on all types of media that can be accessed by a user / group, not just images.
  • The Images|Default Registry entry only specifies a maximum size of an image that a user / group accesses by default; it does not restrict them from accessing larger images.

When the Maximum Registry entry has been specified for a user / group, the affected media will not be accessible to the user / group either:

  • Using the Multimedia>Launch Viewer menu option - items greater in size than the maximum size specified will be greyed out and inaccessible

    -OR-

  • From the Resolutions tab of the Multimedia module - a warning message will display when a user attempts to view items that exceed the maximum size.

For the purposes of setting a maximum size, PDFs are treated as images, so long as an Images|Include Registry entry specifies PDF, e.g.:

System Setting Multimedia Images Include PDF;DNG
