- Improved cache handling to reuse existing lookup requests and reduce unnecessary repeated work.

Compatibility

Changes to previous v1.2.0.

🖼 Image preview window — Clicking a Google Lens result can now open an image preview window without immediately leaving the Lens results page.

🔎 Original image detection — The extension searches for the original/source image behind a Lens result and displays it when available.

📸 Lens thumbnail fallback — If the original image cannot be retrieved, the visible Lens image can still be shown in the preview.

📐 Source vs Lens resolution — Compare the dimensions of the original source image with the Lens image.

⏱ Search status & timing — See when the extension is searching, when an image is found, or when it is unavailable, including search time.

🔗 Improved source controls — Source domains are displayed as clickable pills, with clearer website and image controls.

↔ Preview navigation — Move between Lens results using Previous/Next buttons or the keyboard arrow keys.

➕➖ Minimise preview — Collapse the preview window while keeping it available.

🎨 UI improvements — Refined preview positioning, sizing, status colours, controls and interaction with the sorting menu.

⚡ Improved reliability — Better handling of missing thumbnails, unavailable source images and Google Lens results that don't expose a conventional image URL.
