简介
Quick Image lets you replace or overlay any image on any website in seconds - no code, no DevTools.
Who is it for?
• Web designers previewing hero images, banners, and product photos in real layouts
• Marketing teams doing A/B image testing and comparing creative variations
• Anyone who wants to see how a different image would look on a live website
Basic workflow:
1. Add images from folder, clipboard, or right click context menu. Batch adding works.
2. Pick a target from auto-detected images, or shift+T.
3. Navigate with arrows to see how images look.
4. Star the best ones with Shift+Enter
5. Compare starred images with number keys 1-9 (or arrow keys)
6. A/B test to original with Space
7. Right click to see original image name / context / url
Key features:
• Replace any image on a page — works with img elements, srcsets, background images, hero sections, and CSS backgrounds
• Overlay mode — drag a floating image anywhere on the page, resize, rotate, and adjust opacity
• One-click capture — right-click any image on any site to add it to your collection
• Drag & drop or paste images — drop files or paste from clipboard instantly. Batch add folder of images.
• Image controls — opacity slider, object-fit, position, scale, flip, and blend modes
• Keyboard-driven workflow — arrow keys to cycle images, Space for A/B toggle, number keys for quick select
• Global image library — your images are available across all websites
• Replace Target Grid — see all page images at a glance, click to replace any of them
• Works on any website — WordPress, Shopify, Webflow, Squarespace, custom sites, localhost
Images persists in your library through browser restarts and cookie clears, 100% local.
How it works:
Click the Quick Image icon or press Ctrl+Shift+Q to open the panel
Drop, paste, or capture images into your collection
Click a page image to select it as the replace target
Click a collection image to replace it — instantly, no refresh needed
Press Space to toggle between original and replacement (A/B comparison)
Quick Image is designed for speed. Minimal clicks, keyboard shortcuts for everything, and instant visual feedback. Your image collection persists across sessions — build it once, use it on every site.
Perfect for: website mockups, design reviews, image placeholder replacement, visual regression testing, client presentations, e-commerce product photo testing, and creative asset comparisons.
