Wonderplugin Gallery keeps galleries and slides in dedicated custom tables rather than as posts: a galleries table for the gallery row (id, name, layout, options blob) and a slides table for individual image rows (id, gallery_id, image, thumbnail, title, description). The default admin shows one screen per gallery, which keeps the per-gallery editor clean but hides the inventory question.

SleekView Charts reads the Wonderplugin gallery and slide tables directly and turns the catalog into a configurable dashboard. Number cards count total galleries and total slides. Pie cards split galleries by layout type (grid, slider, carousel, lightbox). Bar cards rank galleries by slide count or by post placement. Area cards trace gallery growth across creation date.

Every card reads through the same Wonderplugin tables, so the public-facing layouts continue to render exactly as the plugin configures them. The dashboard sits alongside SleekView's table view of the same dataset.

Wonderplugin Gallery has powered photo galleries on thousands of WordPress sites for over a decade, and its decision to use custom tables paid off for performance: slide rows are indexed by gallery_id and aggregations run fast. The cost is that the default admin treats every gallery as a destination instead of a row, so cross-cutting questions never get asked. SleekView Charts reads the same tables and gives the catalog one dashboard.

A donut of layout mix exposes the consolidation case. A horizontal bar ranks galleries by slide count, surfacing both overstuffed and empty galleries. An area chart of creation date reveals delivery cadence.

A single number KPI on total slides gives owners catalog scale at a glance. None of this requires new instrumentation. The data has been in the tables the whole time, the dashboard just makes it legible at the inventory level.
