Last month, Posterino 6.0 introduced the Liquid Glass design language. Today, Posterino 6.1 shifts focus from looks to functionality with a complete overhaul of the Tile layout algorithm.

Smarter Tile Layout
The Tile layout has always been about creating magazine-style arrangements that respect your images’ original proportions. With 6.1, I’ve redesigned the algorithm from the ground up to better balance three competing goals: preserving aspect ratios, maintaining image sequence, and filling available space.
The new algorithm is more intelligent about how it arranges images. It minimizes cropping while making efficient use of the canvas, and handles mixed orientations more gracefully than before. You’ll notice the difference immediately when working with varied aspect ratios.
What really makes this release shine is the new level of control. The Inspector now includes a Crop & Fill setting with three presets—No Crop, Minimal Crop, and Fill Page—plus a Custom mode for fine-tuning. You can also choose between horizontal and vertical layout directions, opening up new creative possibilities for tall formats.
Two New Templates
San Andrés and Studio Noir join the template collection in this release.

San Andrés is inspired by the steep streets of its namesake. Images flow in tall columns with generous spacing and no cropping—perfect for portraits or dynamic scenes that benefit from vertical motion.

Studio Noir transforms your portraits into striking black-and-white compositions. It automatically removes backgrounds and places each subject against a deep black backdrop for a timeless studio look. This template requires macOS 14 or later for the automatic processing features.
Other Improvements
Beyond the headline features, 6.1 includes interface refinements across the main menu, document canvas, and inspector panels. The Layout menu now correctly limits Scale Down and Scale Up commands to Square Grid layouts only, and the Command–L shortcut for Show All has been restored. The inline inspector also now hides during drag operations to stay out of your way.
Conclusion
This release represents a significant step forward for Posterino’s layout capabilities. The new Tile algorithm is something I’ve been working towards for a while, and I’m pleased with how it handles real-world image collections.
A special thanks to the beta testers whose feedback helped refine these features. Looking ahead, I’m continuing to explore refinements to the manual layout process and alignment guides.
