+# Go Live >> Social Media ||20
+
+Having a nice preview image for social media can be very helpful.
+For that reason Rocket creates those automatically with the title, parent title, section and your logo.
+
+It will look like this but with your logo
+
+<img src="{{ socialMediaImage }}" width="1200" height="630" alt="Social Media Image of this page" style="border: 1px solid #000" />
+
+There are multiple ways you can modify it.
+
+## Setting it via frontMatter
+
+You can create your own image and link it with something like this
+
+```
+---
+socialMediaImage: path/to/my/image.png
+---
+```
+
+## Providing your own text
+
+Sometimes extracting the title + title of parent is not enough but you still want to use the "default image".
+
+You can create an `11tydata.cjs` file next to your page. If your page is `docs/guides/overview.md` then you create a `docs/guides/overview.11tydata.cjs`.
+
+In there you can use the default `createPageSocialImage` but provide your own values.
+
+```js
+const { createPageSocialImage } = require('@rocket/cli');
+
+module.exports = async function () {
+  const socialMediaImage = await createPageSocialImage({
+    title: 'Learning Rocket',
+    subTitle: 'Have a website',
+    subTitle2: 'in 5 Minutes',
+    footer: 'Rocket Guides',
+  });
+  return {
