Thumbnail Management

This section controls WordPress thumbnail generation, size usage, and cleanup tooling. It helps reduce disk usage and prevents unnecessary image variants.

Where to configure

1. Open ZiziCache → Images.
2. Switch to Thumbnail Management.

Thumbnail Settings

• Enable Thumbnail Prevention — Prevents WordPress from generating unnecessary thumbnail sizes.
• Disable Big Image Threshold — Stops WordPress from automatically downscaling large images (default 2560px).
• Disable EXIF Auto-rotation — Prevents automatic rotation based on EXIF data.

Srcset compatibility

If Generate responsive images (srcset) is enabled in Image Optimization, only the sizes allowed in Thumbnail Sizes will appear in srcset attributes.

Thumbnail Sizes

This list shows registered thumbnail sizes and allows disabling sizes that are not used by your theme or plugins.

• Disabled sizes are not generated on disk.
• Disabled sizes are excluded from srcset and preload hints.
• Reduces storage and unnecessary processing.

Usage Analysis & Cleanup

• Analyze Usage — scans usage and displays results.
• Preview Cleanup — shows what would be deleted.
• Execute Cleanup — performs deletion after confirmation.
