SleekView reads the standard WordPress key _wp_attachment_image_alt, which is exactly where ShortPixel writes its generated alt text. This means the dashboard also reflects manually entered alt text from editors, so the coverage KPI is a true measure regardless of how the alt was populated.

No. ShortPixel's bulk run, credit consumption, and API calls are entirely inside the plugin. SleekView only reads the resulting postmeta rows. Pausing or resuming the bulk job in ShortPixel works exactly as it does without SleekView installed.

By default the cards filter to image mime types. SVG can be included or excluded depending on whether the team treats it as an image for accessibility. PDFs are not images and are excluded from the coverage KPI to keep the number meaningful.

Yes. The media library does not directly link attachments to parent post types, but post_parent on wp_posts attachments can be joined back to the parent post. Cards can then filter to attachments used by a specific post type if the editorial workflow demands that granularity.

Images referenced directly in post content without an attachment record live outside wp_posts and are not tracked. ShortPixel mainly works on attachments, so the dashboard reflects ShortPixel's actual scope. Inline-image gaps need a separate audit.

Yes. post_modified updates whenever an attachment's alt text changes, regardless of whether ShortPixel or an editor wrote it. This is usually the right behavior: the trend reflects total work done on alt text, not just the ShortPixel-attributable share.

Yes. SleekView views and data sources are per-site by default. Each subsite reads its own attachments under its own table prefix. A network admin can also build a network-wide source if ShortPixel is processing a shared media library across the network.

ShortPixel's progress screen tracks the bulk job. SleekView tracks the resulting database state. The two are complementary: ShortPixel reports how many images its current job has processed, SleekView reports how many images in total currently carry alt text, including past runs and manual edits.
