The GNOME Volume Manager mounts the contents of your USB camera, treating the memory of your camera as it would any file storage device. When I tried it with an Olympus digital camera, my images were available from the /media/usbdisk/dcim/10 0olymp directory. Figure 8-16 shows an example of the gthumb-import window displaying the images from a digital camera.

With your camera connected and the gThumb window open, here are some things you can do with the images on your camera:

• Download images — Click a single image or select Edit ^ Select All to highlight all images from your digital camera. Then select File ^ Import Photos. From the Import Photos window you can select the destination where you want the images to be downloaded. As an alternative, you can download selected images to a folder on the GNOME desktop.

• View Slideshow — Select View ^ Slide Show. A full-screen slideshow appears on your display, with the images changing every few seconds. The toolbar that appears at the top lets you display information about the photo name, date, and size (click Image Info), go forward and back through the images, and zoom in or out.

• Manipulate images — Double-click an image to open it, and select the Image menu. That menu offers a set of tools for enhancing, resizing, cropping, or otherwise transforming the image. You can also adjust the color balance, hue/saturation, and brightness contrast.

• Assign categories — With an image selected, click the Categories button. The Categories pop-up window lets you assign the image to a category to help you organize your photos. Assign available categories (such as birthday, family, holidays, or games) or click New and add your own categories.

Once images are downloaded to your computer's hard disk, you can continue to work with them using gThumb or use any of a number of tools available for manipulating digital images (GIMP, KView, and Kuickshow, to name a few).

NOTE: If you have a camera that saves images to a floppy disk, just insert that disk into your disk drive and the contents of the disk should open automatically on your desktop. In addition, if your camera saves images to SD or CF cards, you can purchase a USB card reader and view these files from Linux.
