+
+This note demonstrates how to properly embed an image in Nextcloud Notes so it's visible in the browser interface.
+
+We'll include the sample red square image we created earlier using both Markdown and HTML methods.
+
+## Method 1: Markdown Image Syntax
+![Sample Red Square Image](.attachments.{note_id}/sample_image.png)
+
+## Method 2: HTML Image Tag
+<img src=".attachments.{note_id}/sample_image.png" alt="Sample Red Square Image" width="300" />
+
+## Image Path Details
+The image is stored at: `/Notes/.attachments.{note_id}/sample_image.png`
