How do I add a photo or video to my post?

1. In Create post, drop your files on Drop photos or a video here, or click it to pick them. Open Create post
2. Or open Media and press Use in post on any photo or video. Open Media

Facebook and Instagram take up to 10 photos, LinkedIn and Threads 20, and TikTok 35 as a slideshow. A network that takes fewer posts the first ones. Or add 1 video. YouTube takes a video only.
