Hi. Only got my S3 this weekend, and can't find a way to stop the gallery from adding files that are stored on other devices from my WiFi connection. From reading forums, there is things I could do to stop sharing files from a pc, but it still reads files from my NAS drive. I obviously don't want to stop the NAS from sharing files, but I don't want it booting up every time I load the gallery. Thanks for any info.
