The mrsidviewer application is a very simple Windows application for viewing images in all of the formats supported by the SDK, including MrSID and JPEG 2000.
NOTE: The mrsidviewer application is available on Windows SDKs only.
The viewer may be invoked from the command line:
C:\>mrsidviewer image.sid
Normal drag and drop operations are also supported.
The (classical) metadata for the image can be displayed via the Options | Metadata menu item.
