Attaching media to posts

Upload images or MP4 video, attach from Google Drive, or request AI images.

In the post editor, use Attach media to upload from your device or pick a file from Google Drive (after connecting Drive under Integrations). Supported uploads: JPG, PNG, GIF, WebP (up to 50 MB) and MP4 video (up to 200 MB).

AI images

In your sprout tree, request one professional 16:9 image per post on demand at no extra credit cost. Sparky generates it in the background while you review the draft.

Media is stored on SparkVox (Cloudflare R2). AI images use fal.ai FLUX with Google Imagen 4 as fallback. When you approve, attached or generated media publishes with your post to LinkedIn, Buffer, or Publer if connected.
