Caption Gallery Slider

Caption Gallery Slider is an Obsidian plugin for turning a fenced gallery code block into a native-feeling media slider for local images and videos.

Its main idea is simple: keep media in your vault, keep captions as ordinary Markdown notes, and edit those captions directly inside the gallery.

This release is desktop only. The interface relies on hover controls and pointer input, so mobile support is planned for a later version, after dedicated touch testing.

Features

• Local image and video galleries from a folder, an explicit file list, or both.
• Editable Markdown captions stored as regular vault notes.
• Internal links and hover previews inside rendered captions.
• Preview thumbnails, plain dot navigation, and adaptive slider navigation.
• Video playback controls with play, mute, loop, progress, and saved fragment ranges.
• crop and fit view modes, rotation, manual crop pan/zoom, and fullscreen view.
• Caption panel below, above, left, or right of the media; a side caption suits portrait images.
• Resize handles for the media viewport and caption panel.
• Theme-aware UI based on Obsidian CSS variables.

Basic Syntax

```gallery
gallery_id: vacation
dir: Attachments/vacation_2026
list:
  - Attachments/special.png
sort: name
navigation: preview
view: crop
view_height: 420
caption: bottom
caption_size: 96
```

gallery_id is required. It is used as the namespace for caption notes, so the same media file can have different captions in different galleries.

At least one media source is required:

• dir: scans a vault folder recursively.
• list: adds explicit vault paths.
• both sources can be used together.

Options

The other caption dimension follows the gallery: a bottom or top caption is as wide as the note, a side caption is as tall as the media and the arrows. A side caption needs a gallery at least 440 px wide; in a narrower one it moves below the media. In a hover preview a side caption stays on its side and takes half of the width. The older caption_height option still sets the height of a bottom or top caption.

Caption Notes

Captions are not stored inside the code block. Caption Gallery Slider creates Markdown notes lazily when you first edit a caption.

By default, the caption folder is configured in:

Settings > Community plugins > Caption Gallery Slider > Caption folder

Each caption note contains frontmatter for gallery metadata and optional media state, followed by a normal Markdown body. This means captions can include:

• [[internal links]]
• formatted text
• lists
• headings
• backlinks and search results like regular notes

Supported Media

Images:

• jpg
• jpeg

Caption Gallery Slider currently works with local vault files. Remote image URLs, remote videos, YouTube embeds, grid layouts, slideshow autoplay, and audio support are planned as future work.
