You should be able to connect the phone via a USB cable to your computer. You may have to download the driver from LG and install that on the PC. Then you enable MASS STORAGE on the phone; that will connect to the SD card. It should appear as an extra disk drive. You can then transfer files back and forth.
Send pics in an email to an account (gmail) you have set up. That should allow you to save the pics to your SD card.
Best of luck.
