Site Grayscale Toggle lets you turn your entire site grayscale and give visitors a clear on/off switch. It’s built to be CSP-friendly (no inline JS) and to avoid a flash-of-unstyled-content by injecting the initial state on the server side.
Features: 
– Grayscale filter site-wide via <code>html.is-grayscale { filter: grayscale(var(--sgt-level)); }</code>. 
– Intensity control (0–100) from Settings → Site Grayscale. 
– Show/Hide floating toggle button (bottom-right by default). 
– Shortcode: <code>[grayscale_toggle]</code> to place the switch anywhere (headers, menus, footers, blocks, widgets). 
– Remembers visitor preference with <code>localStorage</code> across pages. 
– CSP-safe: no inline JS; initial state added server-side to <code><html></code> to avoid FOUC. 
– Lightweight, theme-agnostic; works alongside most caching/CDN plugins.
Use cases include memorial/monochrome modes, accessibility preferences, or design experiments that you want users to control.

A simple gallery with one really cool feature: ZOOM!
A custom template for FooGallery which allows your visitors to magnify your images with a magnifying glass-like effect.
Like other FooGallery templates you can customize the image size, border styles and shapes. With ZOOM! You can also customize the lens size, lens border, shadow depth. You can also set your thumbnails to have a grayscale or blurred effect either on load or on hover. Blur/grayscale only effects the thumbnail, so that when you look through the magnifying glass you still have a sharp, crisp, and full-color image magnified.
