Unite Flex Gallery

Description

Unite Flex Gallery is a free, all-in-one photo gallery and video gallery plugin for WordPress. Build masonry galleries, justified tile grids, carousels, sliders and full video galleries — then embed them anywhere with a block or a shortcode.

It runs on a mature, fast JavaScript gallery engine wrapped in a WordPress admin that anybody can use. Every setting comes with a plain-English description, options are grouped into logical sections, and the items manager works like a familiar file explorer. No documentation hunting, no guesswork.

Galleries are responsive by default, touch and swipe enabled, and include modern extras such as pinch zoom, pan, fullscreen and a flexible lightbox in wide or compact styles.

Nine Gallery Layouts, One Plugin

Pick the layout that fits your content and switch any time with a single click — your images and settings stay put.

• Tiles – Columns — a masonry-style photo gallery that packs any mix of image sizes into tidy columns. Tiles can sit flush together or with spacing between them.
• Tiles – Justified — a justified image gallery with perfectly straight edges on every row, like a photo magazine spread.
• Tiles – Grid — a uniform grid gallery where every tile is the same size, with paging navigation between panes.
• Carousel — a smooth, touch-friendly image carousel that scrolls endlessly and opens items in the lightbox.
• Default Theme — the classic gallery: big preview image, thumbnail strip, caption text and control buttons in one row.
• Compact Theme — a minimal gallery frame that lets you place the thumbnail panel on any side you like.
• Grid Theme — a large preview paired with a multi-column thumbnail grid panel.
• Slider — a clean image slider with navigation bullets, ideal for hero sections and blog posts.
• Video Gallery — a dedicated video gallery layout with three navigation styles on the right.

WordPress Video Gallery Support

Unite Flex Gallery is a real video gallery plugin, not just an image gallery with a video bolted on. Paste a link and the plugin fetches the thumbnail and handles the player for you.

• YouTube video galleries
• Vimeo video galleries
• Wistia
• SoundCloud audio
• Self-hosted HTML5 video (MP4, WebM, OGG)
• Custom iframe embeds

Mix videos and images freely inside the same gallery.

Touch-Enabled Responsive Lightbox

Every gallery type ships with a built-in responsive lightbox. Choose a wide or compact lightbox style, swipe between items on mobile, zoom into detailed photos with pinch or buttons, pan around, go fullscreen, and show titles and descriptions in the text panel.

A WordPress Gallery Admin That Explains Itself

• Galleries manager — create, duplicate and organize unlimited galleries
• Items manager — drag and drop images, edit titles and descriptions in place
• Settings with help — every option grouped logically and documented inline
• Gutenberg block and shortcode — embed anywhere with the block, or paste [unitegallery mygallery] into a classic editor or page builder

Fast and Lightweight

Thumbnails load first and full-size images load on demand, so a page with a large photo gallery stays quick. Layouts adapt to their container and to the screen, and thumbnail panels collapse gracefully on small devices.

Developer Friendly

A full JavaScript API with events and methods lets you play, pause, zoom, switch items, enter fullscreen or swap out every image on the fly. GPL v3 licensed with no lock-in.

Perfect For

Photography portfolios, wedding and travel photo blogs, product showcases, real estate listings, restaurant menus, event albums, video channels, agency work galleries and any WordPress site that needs images and video presented well.

External services

This plugin embeds third-party video and audio in galleries. Those providers are only contacted when a gallery (or the admin video dialog) includes an item of that type. The plugin does not send site visitor account data to these services; it sends the video or track identifier needed to load the embed, plus standard HTTP request data (such as IP address and browser information) that those providers may log according to their own policies.

YouTube (Google)

• What it is used for: Playing YouTube videos in the gallery lightbox/player, loading the YouTube IFrame Player API, and fetching default thumbnail images in the admin “Add Video” dialog.
• What data is sent and when:
  • On the public site, when a gallery item is YouTube, the visitor’s browser loads https://www.youtube.com/player_api and embeds the video using the YouTube video ID stored in the gallery item.
  • In the WordPress admin, when you search for a YouTube video by ID or URL, the browser requests thumbnail images from https://img.youtube.com/vi/{VIDEO_ID}/… to validate the ID and show a preview.

• Privacy policy: https://policies.google.com/privacy

Vimeo

• What it is used for: Playing Vimeo videos in the gallery and looking up Vimeo video metadata in the admin “Add Video” dialog.
• What data is sent and when:
  • On the public site, when a gallery item is Vimeo, the visitor’s browser loads the Vimeo player script from player.vimeo.com and embeds the video using the Vimeo video ID stored in the gallery item.
  • In the WordPress admin, when you search for a Vimeo video, the browser requests https://www.vimeo.com/api/v2/video/{VIDEO_ID}.json with that video ID.
• Service provider: Vimeo.com, Inc.
• Terms of service: https://vimeo.com/terms
• Privacy policy: https://vimeo.com/privacy

Wistia

• What it is used for: Playing Wistia videos in the gallery (via the bundled Unite Flex Gallery media library) and fetching Wistia video metadata in the admin “Add Video” dialog.
• What data is sent and when:
  • On the public site, when a gallery item is Wistia, the visitor’s browser loads https://fast.wistia.com/assets/external/E-v1.js and embeds the video using the Wistia media ID stored in the gallery item. Item previews in the admin items manager may load https://fast.wistia.net/embed/iframe/{VIDEO_ID}.
  • In the WordPress admin, when you search for a Wistia video, the browser requests https://fast.wistia.net/oembed with the Wistia media URL/ID to retrieve title and thumbnail information.
• Service provider: Wistia, Inc.

SoundCloud

• What it is used for: Playing SoundCloud audio tracks in the gallery via the bundled Unite Flex Gallery media library.
• What data is sent and when: When a visitor opens or plays a SoundCloud gallery item, the browser loads https://w.soundcloud.com/player/api.js and an embedded player iframe from https://w.soundcloud.com/player/ containing the SoundCloud track ID stored in the gallery item (for example http://api.soundcloud.com/tracks/{TRACK_ID} in the embed URL). Autoplay and player display options are passed as query parameters in that embed URL.

MediaElement.js (bundled)

• What it is used for: HTML5 video playback controls when a gallery item uses a self-hosted HTML5 video file (MP4, WebM, or OGG).
• What data is sent and when: When a gallery contains HTML5 video items, the visitor’s browser loads MediaElement.js (and optionally hls.min.js for HLS streams) from files bundled inside this plugin. These assets are served from your own WordPress site. No third-party CDN is used, and no data is sent to external MediaElement or MPEG-DASH related services. MPEG-DASH support (dash.js) is not included in this plugin.
