+description: Create beautiful interactive image gallery using Markdown
+date: 2023-08-26 00:00:00+0000

+---
+
+Hugo theme Stack supports the creation of interactive image galleries using Markdown. It's powered by [PhotoSwipe](https://photoswipe.com/) and its syntax was inspired by [Typlog](https://typlog.com/).
+
+To use this feature, the image must be in the same directory as the Markdown file, as it uses Hugo's page bundle feature to read the dimensions of the image. **External images are not supported.**
+
+## Syntax
+
+```markdown
+![Image 1](1.jpg) ![Image 2](2.jpg)
+```
+
+## Result
+
+![Image 1](1.jpg) ![Image 2](2.jpg)
