Originally you have to use itunes to copy files but there is apps on the apps store that will allow you to do it without syncing through itunes..
RheaRhea, I just love being able to have all of my photos on my phone to show to people. Let's make sure you can do the same. Here is some info from Apple on how to transfer the files: http://bit.ly/UeIK67.

Go to the iTunes Store.
Plug your iPhone into your PC (use the USB cable provided with the phone).
Next, look for the iTunes Store bar-icon towards the top right ( where it is on my PC screen).
Next to it an iPhone bar-icon will pop up. Click it and follow instructions. After that, your phone will auto sync photos and tunes when you
plug it into iTunes.
Gina7239 is absolutely correct. I just hook the iphone via usb port, shows as another drive, you then select which photos you want to either "copy" or "move" to or from the iphone. it is very simple to do.
Make sure you have the iphone on so as not to be on auto screen off or sleep mode.
The iphone has to stay connected and fully on to do what you desire.
