cam2pc can be used to display your images (JPEG, TIFF, GIF, BMP and PNG files) in a full-screen viewer. The simpler way is to associate cam2pc with those image types. File associations were prompted to you during installation but you can change them whenever you like. To change them dispay the Options and then go to the Shell Integration section. Select the associations you want to activate (or use the Select All button) and then click OK. From now on, double clicking an image file in the Explorer it will launch cam2pc.
