One gallery, many looks

Layout is only part of the story.

Each gallery can have its own appearance. Version 0.4.0 introduces design presets, gallery-specific overrides, live Gallery and Lightbox previews, multiple frame styles, backgrounds, shadows, corner radius, caption styling, and per-gallery Lightbox appearance.

So two galleries can use the same layout while looking completely different.

Here I would add another 2–3 smaller gallery examples, deliberately using the same or similar images but different design settings. That will demonstrate the preset/design system much better than screenshots of the backend.

For example:

• Minimal / clean presentation
• Framed / editorial presentation

• Dark or contrast presentation

  The exact names do not have to correspond to preset names in the backend. On the public page they can simply describe the visual result.

What you can do with it

• Five responsive layouts: Masonry, Mosaic, Patterned Mosaic, Justified Rows, and Uniform Grid
• Design presets with per-gallery customization and live preview
• Configurable spacing, frames, backgrounds, shadows, corners, captions, and Lightbox appearance
• Optional GLightbox
• Progressive loading and configurable Load More
• Gallery-specific Caption and Alternative Text overrides linked to TYPO3 files
• Grid, List, and Table image-management views in the TYPO3 backend
• TYPO3-native multilingual metadata workflow
• English, German, French, Spanish, and Russian backend interface translations
• Backward-compatible upgrade path from earlier releases

Installation

Composer — recommended

From your TYPO3 project root:

sudo -u www-data -H composer require anatolkin/anatolkin-mosaic-gallery:^0.4

sudo -u www-data -H php vendor/bin/typo3 extension:setup

sudo -u www-data -H php vendor/bin/typo3 cache:flush

The package name is:

anatolkin/anatolkin-mosaic-gallery

TYPO3 Extension Repository

You can also install the extension directly from the TYPO3 Extension Repository.

Extension key: anatolkin_mosaic_gallery

On a non-Composer TYPO3 installation, open Admin Tools → Extensions, search for Anatolkin Mosaic Gallery, and install the current release.

Manual ZIP installation

The release ZIP is also available from GitHub and TER and can be uploaded through the TYPO3 Extension Manager.

Updating from an earlier version

Version 0.4.0 is designed to remain backward compatible with existing galleries.

Updating from 0.3.1 to 0.4.0 does not require a database migration. Existing galleries without the newer layout or design settings continue to use backward-compatible defaults.

Legacy Quick Captions also remain supported. The newer UID-linked metadata workflow is available when you want more stable per-image Caption and Alternative Text management.

For Composer installations:

sudo -u www-data -H composer require anatolkin/anatolkin-mosaic-gallery:^0.4 -W

sudo -u www-data -H php vendor/bin/typo3 extension:setup

sudo -u www-data -H php vendor/bin/typo3 cache:flush

Feedback & contributions

I originally built Anatolkin Mosaic Gallery because I wanted it for my own websites. I continue developing it in much the same way: by using it, finding things that could work better, and gradually improving them.

If you use the extension and have an idea, find a bug, or would like to see another feature or layout, please let me know.

Feedback, contributions, and support are always appreciated.
