ImageViewer is an image viewer inspired by Google Photo’s.
It may also look familiar to users of Ebay.com or Tweakers.net.
It provides a modal for images, similar to modals as lightbox, colorbox and fancybox, just in a somewhat more abstract way.
Features
- Smooth dragging and panning images.
- Support touch devices.
- Double tap to zoom in/zoom out.
- Pinch in / pinch out to zoom in/out.
- Snap view for easier panning and zooming experience.
- Exposed API to control zoom programmatically.
Anti-Features
- Clean user interface, no bells, no whistles, no horns.
- Lightweight code (no PHP, 2 JS files and 1 CSS file).
- No settings page (really).
- No database queries.
Upstream Project
You can look at Github for the original code.
This project is integrated in this WordPress plugin and all ready to use.
Compatibility
This plugin is compatible with ClassicPress.
Contributions
This plugin is also available in Codeberg.
Installation
- Install the plugin through the admin page “Plugins”.
- Alternatively, unpack and upload the contents of the zipfile to your ‘/wp-content/plugins/’ directory.
- Activate the plugin through the ‘Plugins’ menu in WordPress.
- That’s it.
It should just work on the standard WordPress gallery and images.
This plugin expects the same html layout as lightbox, colorbox and fancybox. The image/thumbnail should be inside a link, an a element.
That link should point to the main media image, not the attachment page or a custom link. Only when the link points to an image file, it will show the viewer,
You can go to Gallery > Other Options > Lightbox Effect-tab and select None for the Lightbox Effect.
This code should help you, you can change these default values and put this PHP code in the functions.php file of your theme (preferably a child theme).
<?php
function imageviewer_custom_options() {
?>
<script>
imageviewer_custom_options = {
zoomValue: 100,
snapView: true,
maxZoom: 500,
refreshOnResize: true,
zoomOnMouseWheel: true
};
</script>
<?php
}
add_action( 'wp_footer', 'imageviewer_custom_options' );
?>
