The ImageOptim WordPress plugin sends each upload to the ImageOptim API and writes the result on the attachment in wp_postmeta, including the optimized URL, the size before and after, and the queue state for pending and failed entries. The plugin's settings screen handles the API key and global behaviour, but the per-attachment list still uses default WordPress columns, so per-image savings and queue state live behind individual file dialogs.

SleekView reads the same postmeta keys ImageOptim writes and pivots them into proper columns on the attachment row. Original size, optimized size, percentage saved, queue status (pending, optimized, failed), API response time, and last optimized date all become sortable. Saved views like 'failed optimizations to retry', 'images pending for more than an hour', or 'biggest savings of the quarter' load in one click and can be shared with the team. A queue lane column makes the API throughput visible from the attachment list itself.

Inline actions trigger ImageOptim's own retry function, so retries use the configured API endpoint, quality, and retry policy. Bulk retries, bulk re-uploads, and per-uploader audits all run through the same hooks. The plugin keeps owning the API integration; SleekView gives the team a real list view for the optimization library it already produces.

ImageOptim works in the background. Each upload goes through the API, the result is recorded on the attachment, and the page weight numbers quietly improve. That is the shape the plugin solves elegantly.

The shape it leaves missing is the audit. APIs fail sometimes, queues stall sometimes, and bulk imports drop hundreds of files into the pipeline at once. None of that is visible from the default WordPress media library, which renders the same columns it has since 2010.

A performance lead needs to know which uploads are still pending and for how long. A site editor needs to find and retry the failures from yesterday's migration. An agency needs a per-quarter savings summary grouped by uploader or by month.

SleekView reads the same postmeta ImageOptim already writes and gives the team a flat, sortable, filterable list with savings, status, and queue lane as proper columns. The plugin keeps owning the API call; the table makes the result of that work legible at the scale the API runs at.
