Here's a simple way to transfer files from the LG VX5500 to the computer:

1. Download BitPim here and install on your computer.
2. Start BitPim
3. Tether the phone to your PC with a standard micro USB cable. BitPim will autodetect the VX5500.
4. Go to the View menu and select View File System.
5. Browse to the brew / mod / 10888 folder, right-click on each picture in the right pane, and select Save to save them to a folder on your computer.
Unfortunately, you need to save the pictures one by one, so if you have a lot of pictures it will take a while. source
