GithubSimple Image Slider
Simple Image Slider is a lightweight Obsidian plugin that renders a group of image embeds as a clean swipeable slider with captions. It can also show captions for ordinary image embeds.
It is intentionally small. It supports Obsidian image wikilinks, click navigation, keyboard navigation, swipe/drag navigation, and captions. It does not include thumbnails, fullscreen mode, autoplay, video/audio/PDF support, annotations, compression, compare mode, or a settings panel.

Features
- Render multiple Obsidian image embeds as one slider.
- Swipe or drag horizontally to move between images.
- Click the counter to open an image list and jump directly to a slide.
- Use left/right keyboard navigation when the slider has focus.
- Keep captions below images so they do not cover image content.
- Hide visual controls by default for a quiet article-style layout.
- Add visible captions to ordinary captioned images without modifying note content.
- Insert a starter slider block from the command palette, then bind it to a hotkey if desired.
Usage
Add an image-slider code block to a note:
```image-slider
![[landscape-lake.jpg|Alpine lake at sunrise]]
![[forest-river.jpg|River through evergreen forest]]
![[red-rock-desert.jpg|Red rock desert trail]]
```
Supported slider line forms:
![[image.png]]
![[image.png|caption]]
![[folder/image.png|caption]]
![[folder/image.png | caption]]
The text after | is displayed as a caption under the image. If a slide has no caption, no caption is shown.
You can also run Simple Image Slider: Insert image slider block from the command palette. To make it faster, bind that command in Obsidian's Hotkeys settings.
Ordinary image captions are also supported:
![[image.png|caption]]

For ordinary images, |300 and |300x200 are treated as Obsidian size aliases, not captions.
Behavior
- One image is shown at a time.
- Previous and next controls wrap around at the ends.
- The counter opens a compact image list for quick slide switching.
- Horizontal swipe or drag changes slides.
- The current image is preserved when the same slider block re-renders after editing.
- Small accidental drag movement is ignored.
- The image uses
object-fit: contain. - The image area uses a stable 4:3 canvas and prioritizes filling the available width.
- Hover effects do not resize, crop, scale, shift, or reflow the image area.
- Missing or unsupported lines are skipped; valid images still render.
- If no valid images are found, the block renders
No valid images found. - Ordinary image captions are added during rendering and do not modify note content.
