Image Gallery Editor

This tool provides a data-first gallery editor that constructs image collections from structured image entries. It does not modify image files; instead it manages metadata such as URL, alt text, captions, dimensions, and per-image ordering, along with global layout settings. Supported layouts include grid, masonry, and carousel, with options for spacing, columns, lazy loading, and lightbox behavior. The result is a reusable data model and export-ready markup suitable for CMS pipelines, static sites, or headless front-ends.

Conceptual workflow: users add images by URL and required alt text, then enrich each entry with captions, width, height, and focus coordinates. Global gallery settings govern the overall presentation. The tool validates inputs, deduplicates URLs, and, when widths are provided, generates responsive variants (srcset) and accessible markup. Exports include an HTML snippet that renders the gallery and a JSON object that can be consumed by a CMS or site generator.

Unique value and use cases: teams benefit from a consistent, verifiable data model, bulk edits, and automatic accessibility checks. The editor accelerates portfolio pages, product galleries, and editorial features by delivering ready-to-integrate markup and data. It differentiates through data-first exports, optional responsive variants, and strict validation, while remaining agnostic to hosting or rendering details. In-scope: data creation, validation, and export; out-of-scope: image editing, hosting, and CMS-specific plugins.
