How to embed
Three ways to add this widget to any site:
1. Quick — paste the iframe
Copy the embed code above and paste it anywhere HTML works — blog posts, sidebars, dashboards. No script tags, no sandbox config, no API key.
2. WordPress
Add a Custom HTML block, paste the embed code. The widget renders in the editor preview and on the live page.
3. Notion / Webflow / Wix / Substack
All these platforms accept iframe embeds. Look for a Web/Embed/HTML block, paste the snippet.
Customising
Use the controls in the right column to change the appearance, then re-copy the embed code. The iframe URL accepts query-string parameters so you can change settings later by editing the URL — no need to re-copy.
Branding
Each widget renders a small "Powered by Wallpapers.com" link in the footer. The link is unobtrusive but cannot be removed in the free version.
Performance
Widgets are served from our CDN with a 5-minute cache. They lazy-load, so they don't block your page's first paint. Total weight is typically under 30 KB.
