Glossary

Plain-English meanings of the terms used across this site.

Active thumbnail — The thumbnail of the photo currently shown in the main image. You can mark it with a border, an underline, a zoom or an opacity change. See General → Active thumbnail.

Alt text — A short text description of an image, read aloud by screen readers and used by search engines. Smart Product Gallery uses the image's title from the Media Library.

Autoplay — The gallery moving to the next photo on its own after a set interval. On by default, and controlled under Gallery Slider.

Block — A single piece of content in the WordPress editor, such as a paragraph, an image or a gallery. Smart Product Gallery adds one block, Product Gallery.

Block theme — A WordPress theme you edit visually in the Site Editor (Appearance → Editor), such as Twenty Twenty-Five. On block themes the gallery is placed through the Single Product template. See Block Themes.

Classic theme — A traditional WordPress theme customized under Appearance → Customize. On classic themes the gallery replaces FluentCart's automatically. See Classic Themes.

Featured image — The main image set on a product. It's the first photo in the gallery and the one shown in the shop.

FluentCart — The WordPress e-commerce plugin Smart Product Gallery works with. It handles your products, prices, cart and checkout.

Global settings — Settings that apply everywhere at once. All of Smart Product Gallery's settings are global: one configuration styles every product.

Lazy loading — Loading an image only when it's about to be seen, instead of all at once when the page opens. It makes pages faster.

Quick view — FluentCart's pop-up on shop pages (the View Options button) for choosing a variation without opening the product page. Smart Product Gallery shows its gallery there too.

Shortcode — A short tag in square brackets, such as [smart_product_gallery], that WordPress swaps for real content when the page loads. It's useful in page builders. See Shortcode.

Slider — A gallery that shows one photo at a time and moves between them. Also the name of the layout that shows only the main image, with no thumbnails.

Template — A saved page layout used for every page of one kind. Single Product is the template block themes use for every product page.

Thumbnail — A small preview of a photo. Clicking or hovering one shows it in the main image.
