Q: I have double the amount of photos on my ipod touch, how do I clean it up?

When you take a photo with photo stream enabled, it is both saved in your camera roll and uploaded to your photo stream.  Since photo stream is turned on, when it is uploaded a copy is streamed back to your device to the photo stream album, resulting in two copies of the photo on your device.

If you want the photos to remain in your photo stream, you can import the camera roll copies to your computer and delete them from your camera roll, as explained here: http://support.apple.com/kb/HT4083.  Then the only copy will be in your camera roll.  The other option is to delete them from your photo stream and only keep the copy in your camera roll on your device.  However, when you do this, the photos are deleted from the photo stream album of all devices and computer connected to your photo stream as well, which defeats the purpose of enabling photo stream.  If you still want to do this, open the photo stream album on your device, tap Edit, tap all the photos you want to delete, tap Delete, then tap Delete Selected Photos.

Thanks. I will give it a try, after I save them all to my laptop lol
