<p>Embed large, detailed SVG diagrams in WordPress with an accessible viewer that supports touch-friendly zooming, panning, and centering. BT SVG Viewer keeps maps, technical drawings, and infographics sharp on every screen, while giving editors a visual preset builder so they can reuse configurations without repeating shortcode attributes.</p>
<h4>Highlights</h4>
<ul>
<li>Interactive zoom and pan controls with keyboard shortcuts and optional slider mode.</li>
<li>Smooth, cursor-focused zoom animations with click-drag panning.</li>
<li>Preset post type with live preview, copy-ready shortcodes, and color pickers for control styling.</li>
<li>Fine-grained shortcode attributes for height, zoom bounds, center coordinates, titles, and captions.</li>
<li>Front-end wrapper classes and CSS custom properties for deep theme integration.</li>
<li>Localized UI and strings in English, German, Spanish, French, and Italian.</li>
</ul>
<h4>Shortcode Overview</h4>
<p>Use the <code>[btsvviewer]</code> shortcode anywhere shortcodes are supported. Pass a direct SVG URL or reference a saved preset ID. All shortcode attributes (height, zoom limits, controls layout, button colors, etc.) can be overridden per instance. See the plugin’s admin Help tab or project README for a full attribute reference and examples. Existing shortcodes created before the rename continue to render, so archived posts don’t need to be touched.</p>
<h4>Preset Workflow</h4>
<p>Create a preset from <strong>BT SVG Viewer <span aria-hidden="true" class="wp-exclude-emoji">→</span> Presets</strong> in the admin. Upload an SVG, tune the controls, tweak button colors, then load the preview to dial in the initial zoom and center point. Save the preset and drop the generated <code>[btsvviewer id="123"]</code> shortcode wherever you need the viewer. Inline attributes always win over stored preset values, making it easy to reuse a baseline configuration.</p>

<p>Shutter Reloaded is an image viewer for your website that works similarly to Lightbox, Thickbox, etc. but is under 10KB in size and does not require any external libraries. It has many features: resizing large images if the window is too small to display them with option to show the full size image, combining images in sets, redrawing the window after resizing, pre-loading of neighbour images for faster display and very good browser compatibility.</p>
<p>This plugin offers customization of the colour and opacity settings for the background and colour for the caption text, buttons text and the menu background.</p>
<p>There are options to enable it for all links pointing to an image on your site (with option to exclude some pages), or just on selected pages. It can be enabled only for image links with CSS class=”shutter” with option to create a single set or multiple sets for each page.</p>
<p>The plugin can also “auto-make” image sets for each Post, so when several posts are displayed on the “Home” page, links to images on each post will be in a separate set. See the built-in help for more information.</p>


Shutter Reloaded

Darkens the current page and displays an image (like Lightbox, Thickbox, etc.), but is a lot smaller (10KB) and faster.
