| Header Photo | 1500 x 500 px | 3:1 | JPEG, PNG |
| In-Stream Photo | 1200 x 675 px | 16:9 | JPEG, PNG, GIF |
Tips:
- Maximum file size: PNG/JPG ≤ 5MB, GIF ≤ 15MB (on mobile/web view).
- Avoid excessively tall images; cropping may occur in the feed.
- Animated GIFs are not supported in profile or header images.
