Where are they located now? The pictures taken by the camera go to /sdcard/DCIM/100MEDIA, the gallery will also display pictures found in /sdcard/Download, as well as /sdcard/Pictures/Screenshots. There are other folders where 3rd party apps will store pictures (Instagram in the Pictures directory, Facebook in the DCIM folder, etc.) but those are the main local locations where the gallery app looks for photos ... it also pulls photos from a few cloud services when you have them set up (Dropbox, Facebook, Flickr, etc.).
