Before you can undertake any image editing, you need to transfer your images to your PC. Depending on the source of the pictures, there are a variety of ways of doing this. We have already looked at transferring images to your PC in Chapter 8, but let's briefly recap the procedure here.
Most modern cameras use memory cards to store the pictures. If you have such a model, when you plug the camera into your PC's USB port, you should find that SUSE Linux instantly recognizes it. Under GNOME, an icon should appear on the desktop and within the Computer Nautilus window, and double-clicking it should display the memory card contents. Under KDE, a dialog box should open asking what you want to do with the contents of the camera memory card.
■ Note Technically speaking, the memory card has been mounted. See Chapter 14 for an explanation of mounting.
If your camera doesn't appear to be recognized by SUSE Linux, you should consider buying a USB card reader. These devices are typically inexpensive and can read a wide variety of card types, making them a useful investment for the future. Some new PCs even come packaged with card readers. Most generic card readers should work fine under Linux, as will most new digital cameras.
If you're working with print photos, negative film, or transparencies, you can use a scanner to scan them in using the XSane image-scanning program, covered in Chapter 8. This works in a virtually identical way to the TWAIN modules supplied with Windows scanners, in that you need to set the dots per inch (DPI) figures, as well as the color depth. Generally speaking, 300 DPI and 24-bit color should lead to a true-to-life representation of most photos (although because of their smaller size, transparencies or negative film will require higher resolutions, on the order of 1,200 or 2,400 DPI).
