Then here's what you do:
1. Download the Aloha (IOS) or Phoenix (Android) Browser.
2. On OF, click on the picture.
3. Press and hold on the enlarged, a download picture popup should appear.
If a post has more than 1 photo, you'll have to click each photo to save them individually in source quality.
For videos:
1. Change the video quality from 720 to original.
2. Let the video play for about 5 seconds or so.
3. Press and hold on the video for a download popup to appear.
4. Save the video.
