-title: Image gallery
-description: Create beautiful interactive image gallery using Markdown
-date: 2023-08-26 00:00:00+0000
-image: 2.jpg
----
-
-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)
