You can get the latest LG drivers from their site-
LG MS695 Support: Find Manuals & Warranty Info | LG USA
That should get you USB connectivity. Once you are connected, select mass storage mode and you'll see two removable drives on the PC. One is the internal storage where your pics are (DCIM folder), the other is the SD card.
To select where the pics are stored in the future, go to the settings menu in the camera. Scroll down to the bottom and you'll find the storage option. Select SD card.
When you're done be sure to eject both drives from the Remove Hardware menu on the taskbar of the PC before unplugging the phone.
