How to download images from infinite-scroll pages
Short answer
A page that adds images while you scroll does not contain them all until you have scrolled past them. Nothing running in the browser can save a file the page never loaded, so the order matters: scroll to the end first, give the last batch a second to settle, then collect. A bulk downloader reads whatever the page holds at that moment, which is why the scrolling has to come first.
Doing it by hand
Scroll to the end of the feed, then right-click and Save image as… on each picture you want, one at a time.
A common variation is to middle-click every image into its own tab first and work through the tabs afterwards — the same number of clicks, just rearranged.
Where that falls apart
- Long feeds unload what is behind you. Some sites drop images out of the page once they are far enough out of view, so the ones near the top can be gone by the time you reach the bottom.
- Nothing tracks what you already saved, so a long session ends with duplicates in some places and gaps in others.
- The context menu gives you whichever copy the browser chose to display, and in a feed that is almost always a small preview rather than the full-size file.
- Two clicks per image is fine for five images and an afternoon for five hundred.
Doing it with ImgDown
Step 1
Scroll to the bottom first
Keep scrolling until the feed stops adding rows, then wait a moment for the last images to finish loading. Everything you scrolled past is now part of the page, and that is exactly what the extension can see.
Step 2
Open the image list
Click the toolbar icon, or press Alt+C to scan only this tab. Every image the page has loaded appears as a thumbnail with its real dimensions underneath.
Step 3
Filter out the interface
Set a minimum width — 400px is a sensible starting point — so avatars, icons, buttons and spacer images drop out and only the content you came for is left.
Step 4
Select and download
Use invert-selection to flip a small pick into a large one, then download everything left in a single pass. Files land in your normal downloads folder.
