ShortPixel records optimization data on each attachment in postmeta keys like _shortpixel_status, _shortpixel_optimized_files, and a per-thumbnail savings array. The Bulk and Other Media screens show progress and totals, but the audit-shaped questions a performance team has after a few months of operation live a layer down.

SleekView Charts reads the same postmeta and turns it into a configurable dashboard. Number cards show total bytes saved across the library. Pie cards split attachments by optimization status. Bar cards rank optimization levels (lossy, glossy, lossless) by use. Area cards trace optimized bytes by upload year so a performance lead can see which sections of the site benefit most from a focused round.

Every card reads through the postmeta ShortPixel already writes, so credit accounting, backups, and the optimization log remain authoritative. The dashboard is an admin companion that answers the cross-cutting questions the per-attachment dialog never could.

Image optimization is a long tail. The first bulk run handles the existing library, but every new upload, every failed retry, every newly enabled format, and every theme change adds rows that drift away from optimal. ShortPixel records all of it on the attachment in postmeta the WordPress media library does not surface as columns, and the bulk dashboard answers only the broad-strokes question of how much has been saved overall.

The audit-shaped questions a performance team has after a few months of operation, which year of uploads has the heaviest tail, which optimization level is doing the most work, what share of the library is still pending, live a layer down. SleekView Charts reads the same postmeta and gives those answers as a dashboard. The plugin keeps doing the optimization work; performance leads, agencies, and editorial teams finally have the dashboard that turns 'we think we are doing well' into 'we can see where we are doing well and where we are not' in a few seconds.
