The full-screen preview opens from the board. Use it to inspect detail, flip through several files, and compare two images or two videos with a split wipe.

## Open the preview

Select a media item on the board, then double-click it, press `Enter`, or right-click and choose **Preview**. If several items are selected, they all load into the preview.

## Zoom, pan and rotate

* **Zoom in** and **Zoom out** go from 25% to 400%. Above 100%, drag to pan; **Reset pan position** recentres.
* **Rotate** turns the file in 90 degree steps.
* **File information** opens the details panel. The **Pinned File Info panel** setting keeps it open.
* With several items, use **Previous** and **Next**, the thumbnails, or the arrow keys.
* `Space` plays or pauses video. Close with `Esc`.

## Compare two files

### Step 1: Select two files

Select exactly two images or two videos: click one, then Shift-click the other.

### Step 2: Open the preview

Press `Enter`, double-click, or choose **Preview**. Compare is on by default.

### Step 3: Move the divider

Move the pointer to drag the divider, no click needed. Model labels sit in the bottom corners.

### Step 4: Use the controls

**Swap sides** flips left and right. **Disable compare** returns to normal navigation.

Compared videos play muted, looped and in sync. Use **Restart comparison videos** and **Play comparison videos**, or press `Space`. An image with a video, or two audio files, can't be compared.

## Step through layers

A generated item with layers, for example from **Qwen Image Layered**, opens on **Original preview**. Use **Previous layer** and **Next layer**, the **Layer N** thumbnails, or the arrow keys.

## Play media on the board

You don't need the preview to play files.

* **Video:** hover or select it, then use **Play video**, the scrub bar and **Mute video**. **Enable automatic looping** mutes, loops and plays it, and is saved with the item.
* **Audio:** click **Play audio** and seek with the position bar.
* Select one video or audio item and press `Space` to play or pause.

Mute and auto-loop are hidden on shared boards and for web-linked media.

## File information

Select one item and click **File information** in its left toolbar to see file details and, for generated media, how it was made. **Focus on item** in the same toolbar zooms to the item. The [Media Browser](https://flashboards.yaroflasher.com/docs/media/media-browser.md) has its own, more detailed panel.

## Large images

A very large image (16 megapixels or more) shows an amber badge, "Large image may slow panning". Click it, then **Create faster preview**. The original is still used for downloads, fullscreen and generation. Choose **Use original** to undo.
