Continuous Image Scanning & Stack Mode

The toggles that change how scanning behaves

Before you launch a scan in Bulk Image Downloader From URL List, it pays to check a few switches in the side panel. Three settings — Continuous Scanning, Stack Mode, and scan duration — quietly control whether your scan keeps running, whether results combine or reset, and how long the whole thing lasts. Get them right and a tricky page becomes a clean, complete collection. Ignore them and you may stop too early or overwrite work you wanted to keep.

Continuous Scanning: keep watching the page

Continuous Scanning tells the extension to keep an eye on the page rather than reading it once and stopping. As new images appear — whether you scroll, the page fetches more content, or a gallery rotates in fresh photos — they land in your list automatically. You do not have to keep re-running the scan to catch what shows up later.

This is especially useful on pages that drip content in over time. Instead of guessing when everything has loaded, you let the scan stay active and collect images as they arrive. When you have what you need, you stop it.

Stack Mode: add or start fresh

Stack Mode decides what happens to your existing results each time you scan. The behavior is simple:

Stack Mode on — each scan adds to your current collection. Results accumulate, which is exactly what you want when you are scanning several pages or sections and building one combined set.
Stack Mode off — every scan starts fresh, clearing the previous results. Use this when each page should stand on its own and you do not want leftovers mixing in.

If you have ever scanned a second page and wondered why the first page’s images disappeared, Stack Mode was off. Flip it on and your scans build up instead of replacing each other.

Scan duration presets and Stop Scan

You also control how long a scan runs. The duration presets range from about thirty seconds up to several minutes, or you can let the scan run until you stop it manually. Short presets are fine for quick galleries; longer windows give heavy, slow-loading pages the time they need to surface everything.

While a scan is active, the side panel keeps you informed with the current mode, elapsed time, and any permission notices. If you reach your goal early — or a page is misbehaving — Stop Scan ends the run on your terms. When the scan completes, a clickable toast slides in showing the count, and tapping it brings you to your results.

Putting them together

These settings work as a set. For a multi-page session, turn Stack Mode on so everything collects into one list, enable Continuous Scanning if the pages load images gradually, and choose a duration long enough to capture slow content — or run until stopped and end it yourself. For a single, simple page, you might leave Stack Mode off for a clean slate and pick a short duration. There is no single correct combination; the right setup depends on the page in front of you. Once your scan finishes, the captured images flow into the same results pipeline where you can filter them, remove duplicates, and send the final set to a download task.
