The phone died. The laptop was wiped. The photos live on a shop you are leaving, a site whose password nobody has, or a listing built four years ago. The originals are still there — every visitor is being served them right now — but saving them one at a time, guessing which version is the full-size one, is an afternoon you will not get back.
Where do the different sizes come from?
A shop rarely shows you one picture. It generates several: a thumbnail for the grid, a medium one for the listing, a large one for the zoom, sometimes a square crop for the social card. They all look the same in a right-click menu. Save the wrong one and you have a 300-pixel file that will never print.
Pictures on a page lists every picture the page uses, loads each one to find its real size, and lets you take the ones worth keeping. It reads the responsive sets too, and takes the widest option in each rather than whatever the page happened to show at your window size.
Why does it miss some pictures?
Because they are not in the page. Many shops build their galleries with script after the page loads, so a server fetching the markup sees a shell with no pictures in it. Nothing can be done about that from a server.
The browser extension solves it from the other side: it looks at the finished page in your own browser, after everything has run, so it sees the gallery that you see. Right-click anywhere and choose Pictures on this page.
Is it legal?
For your own photos on your own shop, yes, obviously. For anybody else's, no. A picture being downloadable does not make it yours: a shop's product photos are the shop's work, using them in your listing is a copyright problem, and most marketplaces will remove the listing and sometimes the account. Supplier photos are usually licensed for resellers, but check the licence rather than assuming.
The honest use for this is recovery and migration: getting your own work out of a platform you are leaving, or back from a site you no longer have the keys to.
What to do with them once you have them
- Check the real size before promising a print size to anyone.
- Clear the background to get a clean version for a new listing.
- Check a PNG is really transparent if it came from a source you do not control.
- Trace artwork into a cut file if the original vector is gone.
Then email the lot to yourself in one go, so they are on the machine you actually work on.
