You have many options for loading photos onto your device:
Sync using iTunes: Probably the simplest way is to use iTunes to sync photos from your computer. We describe this in detail in topic 3: "Sync with iTunes."
Receive as email attachments: While this is not useful for large numbers of pictures, it works well for one or a few photos. Check out topic 18: "Email on your iPhone 4," for more details about how to save attachments. (Once saved, these images show up in the Camera Roll album.)
Save images from the Web: Sometimes you’ll see a great image on a web site. Press and hold it to see the pop-up menu and then select Save Image. (Like other saved images, these end up in the Camera Roll album.)
Download images from within an app: A good example of this is the Wallpaper image shown in topic 9: "Personalize & Secure your iPhone 4."
Sync with iPhoto (for Mac users): If you use a Mac computer, your iPhone 4 will most likely sync automatically with iPhoto.
Here are a few steps to get iPhoto sync up and running:
1. Connect your iPhone 4 and start iTunes.
2. Go to the Photo tab along the top row of Sync Options.
3. Choose the Albums, Events, Faces, or Places you want to keep in sync with the iPhone 4.

Drag and drop (for Windows users): Once you connect your iPhone 4 to your Windows computer, it will appear in Windows Explorer as a Portable Device, as shown in Figure 21-3. Here are the steps to follow to drag and drop photos between your iPhone 4 and computer.

3. Double-click on DCIM to open it.
4. Double-click on 100APPLE to open it.
5. You will see all the images in the Saved Photos album on your iPhone 4.
6. To copy images to your iPhone 4, select and then drag and drop images from your computer into this folder.
7. To copy images from your iPhone 4, select and drag and drop images out of this folder onto your computer.
TIP: Here’s how to select multiple images in Windows.
Draw a box around the images, or click on one image and then press Ctrl+A to select them all. Hold down the Ctrl key and click on individual pictures to select them. Right-click on one of the selected pictures and choose Cut (to move) or Copy (to copy) all of the selected images. To paste the images, press and click on any other disk or folder, such as My Documents, and navigate to where you want to move or copy the files. Then right-click again and select Paste.
