Minimikuva

Minimikuva is a small image that represents a larger media item, page, or dataset. In Finnish contexts it is commonly used to refer to a thumbnail—a compact visual preview that helps users identify content at a glance.

The primary purposes of minimikuvat are to speed up page loading, improve navigation, and provide a visual cue that aids recognition in lists, galleries, search results, and catalogs. They are often displayed in grids and item lists, and may be generated automatically or selected manually by a curator or author.

Generation and formats vary by platform. Minimikuvae can be created by resizing the original image, cropping to a representative area, or producing multiple sizes for responsive layouts. Common file formats include JPEG, PNG, and WebP, with attention to preserving aspect ratio, handling transparency when needed, and applying suitable compression. Accessibility considerations emphasize descriptive alt text and meaningful captions so that screen readers convey the content of the thumbnail.

Storage and delivery approaches differ as well. Some systems store pre-generated thumbnails alongside the original media; others generate them on demand and cache the results, often delivered through a content delivery network to optimize performance. Naming conventions typically append a suffix such as “-thumb” to distinguish minimikuvat from full-size files.

In practice, minimikuvat are ubiquitous in digital media management, including news sites, photo libraries, e-commerce catalogs, and content management systems. They balance visual usefulness with performance and accessibility, while remaining adaptable to various devices and layouts.
