When I do a reverse image search - say by image https://somedomain.com/someimage.jpg - on the page https://images.google.com/, I cannot resize the pre-selected area of the image.
More specifically, this is what happens:
* When I paste the link https://somedomain.com/x.jpg and click the Search button, the service redirects me to a web page whose address appears to be in the format
https://www.google.com/search?vsrid=...&vsint=...&udm=26&lns_mode=...&source=...&vsdim=...&gsessionid=...&lsessionid=...&lns_surface=...&lns_vfs=...&qsubts=...&biw=...&bih=...&hl=...
(e.g. https://www.google.com/search?vsrid=CKmfkdixh6HWKhACGAEiJDIwYmM1NDgyLWI5M2UtNDZjMy04YzRlLWE3N2NiYWUzNWNkODIGIgJyZCgFOOf-n86rn5AD&vsint=CAIqDAoCCAcSAggKGAEgATojChYNAAAAPxUAAAA_HQAAgD8lAACAPzABEIEDGNsBJQAAgD8&udm=26&lns_mode=un&source=lns.web.gsbubu&vsdim=385,219&gsessionid=nAaBFqe7CzxJLu20FyQejjGTNoF-hiF5ilS_4-iE9pOFNIiSwhKurQ&lsessionid=hnXAcNpY60SMFr-p20EuwC5-QTxKfx8BD0A8aHyg8H3OKJ4cvGAnWw&lns_surface=26&lns_vfs=e&qsubts=1760295591739&biw=1024&bih=657&hl=fi&sei=J_rraOHYEpWMxc8P4anMuA8)
The page displays a large view of the x.jpg image and a preselected area that covers only a small part of the view of x.jpg.
* It SEEMS tha I could enlarge the size of the preselected area (by dragging its corners), but it turns out that I can only enlarge it partially, because when I drag some of the corners of the preselected area, the entire image disappears, making further changes impossible.
What is the cause of this irritating behaviour and how could I fix it?

The issue where the entire image disappears when attempting to enlarge the pre-selected area during a reverse image search on Google Images is a known limitation or bug in the web version of Google's image search tools. Many users have observed that resizing the initial selection—usually handled within the Google Lens interface for reverse image searches—results in the image vanishing and no further results being displayed.reddit​

Likely Cause

Google has shifted much of its reverse image search functionality from the classic image search to Google Lens on both desktop and mobile. In the desktop browser interface, Google restricts the resizing tool, likely to encourage users to use the more robust mobile app or Lens platform, where such issues do not occur. This limitation appears to be either a technical oversight or a deliberate design choice, as the mobile Google Lens app does not have the same restriction and allows flexible resizing of the search area.shopify+1​

How to Fix or Work Around

• Use the mobile Google Lens app if possible; it supports free resizing of the search area and does not exhibit this disappearing-image bug.reddit​

• On desktop, try using alternative search engines for reverse image search—such as TinEye or Yandex—which may offer more flexible tools for cropping and area selection without the bug.vivaldi​

• Use the sidebar-based Lens interface by right-clicking an image on a website and selecting “Search image with Google Lens,” which sometimes yields more consistent results on certain browsers.shopify​

• If the image disappears after resizing the area, refreshing the page and performing the reverse image search again (without adjusting the selection) typically restores the search results, though it doesn’t solve the resizing issue.reddit​

This issue is not user-specific and relates to the current design and limitations Google's web-based image search imposes. Using mobile Lens or alternative tools remains the most reliable workaround for now.vivaldi+2​
