My suggestion for the easiest way is to E-mail it to an account you have access to on your computer. However if that is not an option you would have to plug the device into the computer via miniUSB. When plugging your phone into the computer you will need o make sure that you have the drivers for your phone which can be downloaded via Motorola Support, may VZW's website, or if you have a Windows computer it can very well automatically download the drivers via Windows Update up attaching the phone to your computer. From there the phone will look like a "USB Flash drive" to the computer and you can drag and drop or copy and paste your pictures from there.
Hope this helps,
