Image Downloader

The Image Downloader scans the current page for every image — including lazy-loaded, hidden, and CSS background images — and lets you download them individually or as a single ZIP file. In the side panel it's called Download images.

CrawlPilot's Download images screen on a Walmart search page: 83 of 126 images in a grid with sizes and formats, search, sort and grouping, and a Download All button — Every picture on the page, with its size and format, ready to filter and save.

When to Use It

Downloading product images from an e-commerce page
Archiving images from a photo gallery or portfolio site
Collecting reference images for design research
Downloading avatars, icons, or thumbnails from a listing page

Step 1 — Navigate to the Target Page

Go to the page containing the images you want. If it's an infinite-scroll gallery, scroll through the page first to trigger lazy loading before scanning.

Step 2 — Scan for Images

Open CrawlPilot → Images. CrawlPilot scans the page as soon as the screen opens, and the refresh icon scans it again.

CrawlPilot detects images from all these sources:

Source	What's detected
`<img>` tags	`src` attribute; also `data-src`, `data-original` for lazy-loaded images
`<picture>` / `<source>`	Responsive image sources at all breakpoints
CSS background images	`background-image` styles on any element
Video poster frames	`<video poster="...">` attributes
Canvas elements	Converted to PNG data URLs
SVG elements	Extracted or converted to PNG

Detected images appear in a grid with their dimensions and estimated file size.

Step 3 — Filter Images

Use the size filter tabs to focus on what you need:

Filter	Size range
Small	Under 100 × 100 px (icons, thumbnails, avatars)
Medium	100 – 500 px (banners, thumbnails, product images)
Large	Over 500 px (full-quality photos, hero images)

Step 4 — Select Images

Click any image to select it (highlighted border appears)
Click again to deselect
Click Select All to grab all visible images at once

Step 5 — Download

Download Selected — packages all selected images into a .zip file and triggers a download
Click any single image thumbnail — downloads just that image

Downloaded files keep their original filename. ZIP files are named crawlpilot-images-[timestamp].zip.

Supported Formats

JPG · PNG · GIF · SVG · WebP · AVIF

CORS and Protected Images

Some images are hosted on different domains and block direct access (CORS). CrawlPilot routes these downloads through an extension-level background proxy that bypasses CORS restrictions — you see them in the grid and can download them just like any other image.

Note

Images that require authentication (e.g., images behind a login that only load within a user session) may not download correctly outside the browser context.

Example: Downloading Product Images

Goal: Download all high-res product photos from a product detail page.

01
Open the product page in Chrome. Scroll down to ensure all images are loaded.
02
Open Image Downloader → Scan Page.
03
Switch to the Large filter.
04
Click Select All.
05
Click Download Selected.
06
A ZIP file downloads with all product images using their original filenames.

Troubleshooting

Images appear broken in the grid: The image URL is valid but the file couldn't be fetched — this can happen with heavily CORS-restricted CDNs. Try right-clicking the image on the page and saving it manually.

0×0 dimension images appear: These are tracking pixels or invisible elements. They are filtered out automatically.

Video posters missing: Some video players load the poster dynamically. Scroll the video into view and re-scan.
