This may not be exactly what you wanted, but what you could do is set your phone to automatically upload your photos to SkyDrive/OneDrive/MagicalInterwebsCloud. When you take a picture, give it a minute to get uploaded, then delete it from your phone.
If you are taking nekkid pics or something, you can delete the pics off of your phone but they will still be on skydrive. As long as you don't share the photos, nobody should see them. You can always download the skydrive app and view the same pics on your phone from there, but nobody would see them by going to your Picture and Video app on your phone. If you want to put them back on your phone, SkyDrive lets you download them off of the cloud.
