ThumbSpy

ThumbSpy is a lightweight and non-intrusive WordPress plugin that enhances the Media Library list view. It adds a new ‘Thumbnails’ column showing the original image size, all generated thumbnail sizes, their dimensions, and whether they are hard-cropped or resized proportionally.

The plugin also displays the name of each thumbnail size, helping users identify which theme or plugin created it. All entries are clickable, allowing users to view each file version directly.

ThumbSpy now also includes a filter dropdown labeled “Image Filter” to narrow down the Media Library by image MIME type. Filter options include:

• All Images (default)
• JPEG / JPG
• PNG
• WebP
• GIF
• SVG
• Other (for uncommon image types)

Why Use ThumbSpy?

Managing media files effectively improves performance and design consistency. ThumbSpy helps users:

• Troubleshoot image display issues by revealing which plugin or theme generated each thumbnail.
• Optimize server storage by identifying unnecessary thumbnail sizes.
• Confirm proper cropping for media files used in theme layouts.

Ideal for developers, designers, and site managers, ThumbSpy brings clarity and efficiency to WordPress media management.
