A Slidario gallery slider shows photos in a carousel or a grid. Grid and Carousel are free; Masonry (an uneven Pinterest-style grid) and Justified (rows that fill the width) are Pro.

- Create a slider and choose Gallery.
- Add images with Add slides from the media library.
- Pick a style and set Columns (2–6) for grid, masonry and justified.
- Choose in Look whether captions show on hover or always.
On narrow screens, grids show a few photos and a Show all N photos button.
