Screenshot Timeline Player

Screenshot Timeline Player was created (vibe-coded) as a companion app for ShareX's Auto Capture feature. While you can use it with any folder of images, it truly shines when paired with ShareX's automated screenshot workflows. This app lets you view and play back your screenshots in chronological order, turning a folder of images into a timeline you can scrub, play, and explore.

Designed as a ShareX Companion App

Did you know that ShareX, the awesome FOSS screengrabber, has a cool feature called Auto Capture? Auto Capture lets you automatically take screenshots at regular intervals, making it perfect for documenting workflows, monitoring changes, or just capturing everything that happens on your screen—without lifting a finger.

Features

Folder Selection: Load a folder of images (screenshots) at once.
Timeline Playback: Play images in order, like a video.
Playback Controls: Play, pause, go to first/last, next/previous image.
Speed Control: Adjust playback speed (0.5x to 5x).
Thumbnails: See and jump to any image using the thumbnail strip.
Keyboard Shortcuts:
- Space: Play/Pause
- ← / →: Previous/Next image
Multi Delete Select multiple images and delete in one go.

Usage

Open the app in your browser (open src/index.html).
Click Select Folder and choose a folder containing your screenshots or images (ideally, a folder created by ShareX Auto Capture).
Use the playback controls or keyboard shortcuts to navigate through your images.

Supported Image Formats

PNG, JPG, JPEG, GIF, BMP, WEBP

Requirements

A modern web browser (Chrome, Edge, Firefox, Safari).
No installation or backend required.
ShareX (recommended for best experience).

How it Works

The app uses the browser's File System Access API to load images from your local folder.
Images are sorted by their last modified date to create a timeline.
