If she has a Bluetooth-enabled laptop, she'll just need to activate Bluetooth on her phone and computer (in the settings), and make sure that both devices are "discoverable" or "visible" so that they can recognise and communicate with one another. She may be prompted by one device to enter a code on the other in order to pair the two products for sending files. This code should be provided by the first device.
Then it's just a matter of sending the files - in the phone's photo-viewing options there is usually a menu item that says "Send using Bluetooth".
If her laptop does not have Bluetooth, she'll need a Bluetooth dongle, which is a little device that plugs into a USB port to allow the computer to receive files wirelessly.
