I went on general then reset then erase a settings and content. I've managed to get my music and contacts back but can't get my photos. Any ideas? I've got an iPhone 4s iOS 7
If your photos were backed up then restoring from that backup should restore your photos. If your photos were synced via Photostream then once you've configured iCloud on the device and enabled Photostream then the photos should re-sync to your device.
