Heckgalerie

Heckgalerie keeps your images where WordPress already keeps them. A gallery here is a list of ordinary media attachments, not a second media library with its own database tables, its own upload folder and its own backup problem. That has three consequences you can check: srcset and image sizes come from WordPress, alt texts stay the ones you typed in the media library, and the images appear in the WordPress image sitemap without a plugin bridge.

Two things follow from that decision:

• Uninstalling loses nothing. Your images are attachments. Delete Heckgalerie and they are still there, still in the media library, still in every post that links to them.
• Front-end weight stays measurable. All front-end files together are under 15 KB gzipped, and JavaScript is only enqueued on pages that contain a slider or a gallery with the lightbox switched on. Logo bars and the album overview are CSS only, and pages without a gallery load nothing at all.

Two more parts deal with the image files themselves:

• EXIF and GPS data are stripped from the JPEG files WordPress serves for your uploads: from the resized versions, and for photos too small to be resized, from a cleaned copy that WordPress uses in place of the original. Cameras and phones write coordinates, serial numbers and timestamps into image files; a gallery of an event can publish the location of a private address without anyone noticing. Your uploaded original stays untouched. PNG and WebP files are served unchanged.
• A migration assistant for NextGEN Gallery reads the existing NextGEN tables, registers the image files as WordPress attachments without moving or copying them, and rewrites the NextGEN shortcodes in your posts. The old version of each post is kept as a revision, and nothing in NextGEN is deleted.
• Migration from Envira Gallery (Lite), FooGallery and Modula. These plugins already keep their images in the Media Library, so only the image list, the order and a few options (layout, columns, spacing, lightbox on or off) are copied into a Heckgalerie gallery. The assistant also converts their shortcodes and blocks in your posts. It works when the old plugin is already deactivated, and nothing in the old plugin is changed or deleted.

Heckgalerie is part of the Hafenstudios fleet. It works on its own and cooperates with the other fleet plugins once they are active.

Templates

Galleries: grid, masonry, justified and album.
Logo bars: logo grid and single row.
Sliders: crossfade.

The lightbox is included with every template. Block and shortcode use the same renderer, so both produce identical markup.

Albums: several galleries, one page

An album bundles other galleries. Each one gets a tile with a cover image, its name and the image count; one click opens it on the same page, a second click goes back. No subpages, no JavaScript.

Capture data in the lightbox

The lightbox can show a discreet line with camera, aperture, exposure time, ISO, focal length and capture date, for photography sites where that is content. The setting is off by default.

Coordinates are never displayed. Heckgalerie reads exactly those six fields, so a location cannot reach the output even if another plugin writes one into the image data.

Accessibility

The lightbox is a native <dialog> element with full keyboard operation. Every automatic movement stops as soon as the operating system reports “reduce motion”. The admin screens work without JavaScript: the builder is an enhancement, and the shortcode is shown as plain text either way.

Privacy

No tracking pixel, no cookie, no request to another server, in the admin area or on the front end. There is nothing about this plugin to declare in a privacy policy.
