For iPhones (no Androids) - Download YouTube Thumbnail Maker if you haven't already - Open it - Choose YouTube thumbnail - Choose a photo (I do a max of 8 photos but you can do more if you want. If you haven't got any photos, find the ones you want to use.) - Tap on the photo and delete it - Go to 'collages' - Extend the table to however you want it - Tap on any box and add your photos to however you like it - When you're done, tap the two arrows located on the bottom right corner - Adjust the photos to get a good position - When you're finished, tap 'done', located on the bottom right corner - Tap 'add', located on the bottom right corner - Go to the arrow facing up located on the top right corner - Tap 'save image' You're done! You've made your very own FNF cover thumbnail. This'll get a lot more attention from people.
