Yes, you can. If you are using an NI frame grabber, then the NI-IMAQ driver provides the tools to acquire, save, and display images. For FireWire cameras, the NI-IMAQ for IEEE 1394 Cameras driver provides the same functionality.
If you are not using NI hardware or a FireWire camera, then if may be more of a challenge. You can always display an image as a 2D array of pixels with the Picture Control in LabVIEW or as an intensity graph. This will not be as fast as the native Image Display that comes with NI-IMAQ but if you're displaying images from file, then these will work fine.
NI-IMAQ and NI-IMAQ for IEEE 1394 Cameras both come with example programs that show how to display images. There are several examples on the NI Developer's Zone that show how to display images with the Intensity Graph or Picture Control.
