How to Transfer Pictures From a Computer to Your iPhone
The Apple iPhone is a cell phone with all of the added features of an iPod, such as music and video playback. Another feature is the ability to upload photos from an iTunes-equipped computer. Once the iPhone is connected to the computer, you can search for and sync full folders of photos to your iPhone.
Plug your iPhone into your iTunes-equipped computer using the USB cable that came with your iPhone.
Load iTunes. The program may also automatically open once your computer recognizes the connection, depending on your settings.
Click on your iPhone in the source pane on the left. This automatically opens the summary tab for your device.
Select "Manually manage music and videos" if it's not already selected.
Click on the "Photos" tab and select "Sync photos."
Click the drop-down menu and choose "Select Folder."
Choose the photo folders that you wish to sync to your iPhone.
Click the "Apply" button in the lower right-hand corner of the window to begin the sync process.
