ReactionSDK can anchor tap, poll, slider, and rating overlays to still images you already publish—PDP heroes, gallery frames, and landing heroes—using the data-reaction-image host pattern from your campaign embed snippet. The SDK injects the image from your campaign config and reveals the overlay on scroll (no multi-step video timeline on image creatives).
When to use it
- Path-to-purchase signals on product visuals without producing another video.
- Shopify, ClickFunnels, WooCommerce, WordPress: theme sections, blocks, or custom HTML where you control the wrapper around the image.
- Pair with the Commerce funnel pack for three starter intents (Decision Pulse, Post add-to-cart, Pre-checkout).
Host pattern
Create an image campaign in the dashboard, then copy the embed from campaign detail. Mount the empty host node the snippet describes; the SDK fills the image from your campaign configuration (compressed display URL—not original file storage on our side for the typical flow).
Allowlist your production hostnames in the dashboard. Image overlay campaigns are ReactionSDK distribution only (not ReactifySDK embed product).
Next steps
- Quick start (video host) — same SDK script path; swap the element for image hosts when ready.
