Simple. You can either (1) share the photos via bluetooth with your Mac or (2) connect your Droid to your Mac via USB and copy and paste the files.
For sharing via bluetooth, you will need to enable the bluetooth option on your Mac and also your phone. The quicker option is probably hooking up your Droid to your Mac via USB. For that option, plug it into your Mac, then select the option on your phone to use the Droid as disk. You'll then be able to access your files, both your onboard memory and your SD card. You can use finder to access the files that way. (If your Mac gives you some sort of error message when you first attach the phone, click ignore. It's not a real problem.)
