If you want to manage your photos on your Mac, there are generally two ways to do so. The first one involves manual copying of the pictures from your camera’s memory card to a destination on your harddrive. The second one is by using Apple’s sophisticated picture management program iPhoto.
iPhoto offers a lot of very, very neat features. Its ways to quickly browse trough thousands of images it impressive. You can quickly “skim” over a group of pictures by rolling your mouse over the image that represents the group, resuling in a quick glance of all the pictures that are in it. Besides these image viewing and organizing features, iPhoto offers a lot of other neat functions, like the ability to quickly publish photos to an online MobileMe gallery, sharing pictures to and from other users on your local network, perform simple image correction tools, directly order printed materials like photo books, and the creation of very nice and sophisticated slide shows.
But most importantly perhaps, iPhoto is deeply integrated into the Mac OS X experience, and as a result into a lot of other applications. Every program on the Mac that allows you to do something with an image (such as adding an image to a web page in iWeb or pasting a picture in a Word document) generally offers you access to OS X’s media browser, directly showing you thumbnails from iPhoto, ordered in the same way as they are ordered in iPhoto itself. Furthermore, the iPhoto library directly syncs to the iPod and iPhone, and is available for viewing from Apple’s media playback application Front Row.
