AI images

In the post editor, click Attach media and choose From device, From Google Drive, From Dropbox, or From OneDrive. Device upload always works; cloud options require a connected integration. Supported uploads: JPG, PNG, GIF, WebP (up to 50 MB) and MP4 video (up to 200 MB).

AI images

In your project's LinkedIn content strategy, request one professional 16:9 image per post on demand at no extra processing cost. Sparky uses Claude Sonnet to draft a hook-anchored visual scene brief from your post opening, then fal.ai Flux renders the image in the background while you review the draft.

Media is stored on SparkVox (Cloudflare R2). AI images go through Claude Sonnet (visual brief) then fal.ai (Flux). If the brief step fails, a heuristic prompt is used instead. When you approve, attached or generated media publishes with your post to LinkedIn.

• Brief is anchored on your post hook (first lines of the draft)
• Scenes avoid in-image text and generic office stock (laptops, desks, phones)
• One free image per post; regenerates replace the previous generated image
