1) Connect your phone with a USB cable to your computer and copy the files over
2) Upload the photos from your phone to a photo sharing site like Photobucket, or the Google cloud, then download them to your computer. My phone uploads pics to the Google cloud automatically as I take them, so I don’t have to worry about it.
3) Email them to yourself
4) Use a MicroSD card in your phone, which can be removed from your phone and connected to any computer
Use whatever method is easiest for you.
