Thumbnails will never be stretched beyond their intrinsic size (typically `175px`). All available space (in normal mode, or fullscreen mode) will be occupied by the gallery, so more columns than `min_columns` will often be rendered if space allows for more full-sized thumbnails. For normal sized Lovelace cards (`492px` wide), this typically means there'll never be fewer than 3 columns rendered (as otherwise the thumbnails would need to stretch beyond their actual size). Value set must be >= 1. |
