WP ImageViewer

Description

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

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.

FAQ

I have an image, but when I click nothing happens

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,

I am using Nextgen Gallery

You can go to Gallery > Other Options > Lightbox Effect-tab and select None for the Lightbox Effect.

I would like to use custom options for the viewer

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' );
?>

简陋而优雅。Rough yet Elegent

benyangovo November 10, 2024

我的访客大多来自中国大陆，他们访问其他国家的网速会很缓慢。这就是为什么我一直寻找着能够自定义预览图和弹出大图尺寸的插件。其它的画廊插件通常不允许你自行设置这两个尺寸。但这个插件，它选择爬取原版Wordpress超链接指向的图片，这是一种相当巧妙的方式！而且它还提供了其它画廊插件所没有的缩放模块，我不敢相信这个插件目前的下载量只有仅仅300… Most of my visitors are from mainland China, and their Internet speed to other countries is very slow. That’s why I’ve been looking for plugins that can customize the preview image and pop-up large image size. Other gallery plugins usually don’t allow you to set these two sizes yourself. But this plugin chooses to crawl the pictures pointed to by the original WordPress hyperlink, which is a pretty clever way! And it also provides a zoom module that other gallery plugins don’t have. I can’t believe that this plugin has only 300 downloads at present…

Simplicity and Functionality

Cambabutonono October 17, 2023

Why is this plugin great? Does what it says on the box. Integrates seamlessly with standard WordPress functionality. Enhances the standard WordPress functionality without changing it – remove the plugin, and you’re back to standard WordPress without missing or broken blocks. Does not create unnecessary menu items and popups. Does not try to sell you anything. This plugin embodies the simplicity and functionality that WordPress should offer, as opposed to the cluttered, ad-infested, slow, and buggy alternatives out there.

works great

Plugin works great.

Light and Right

Josh Journey July 18, 2021

Dead simple, super light weight and speedy. Pages load faster than other lightbox plugins. Love the addition of navigating via arrow keys and works beautifully on my touch screen monitor. Visually fantastic!

Wonderful plugin
