If Google crawler bots have "found" and indexed an image then Google Image Search/Google Lens,(same thing), will find it.
If the image is behind any kind of barrier, like a paywall or Membership wall or private collection, then Image Search
WILL NOT find it.
--------------------------
FOR COMPUTER... an example:
If using a laptop fingerpad to get a "RIGHTCLICK" use ALT+tap/click pad
.
Go to image #10 > Right click > Click "Search Image"(was Lens)
Click "Find Image Source" (or scroll down for adverts)
Click an image > Scroll down > ENJOY
.
To SAVE...
THIS image is part of a *.MHTML page and you can not save the images easily.
Either log in to Pinterest to save, or TAKE A SCREENSHOT.
If you ever find an image that is *.webp
Use RENAME to change the filename extension
from .webp to JPG and it will then Save.
.
Repeat on Image #4 ....
Unfortunately #4 was never indexed by Google
so cannot be found with Image Search > Find Image,
but you can still save it easily because its filename extension is JPG
.
I used the Screenshot facility my computer here
to Save this blonde beauty we found inside Pinterest, to my computer.
THEN UPLOAD from computer to an Image Hosting website... for example
.
Next:
Rightclick the main uploaded image(NOT thumbnail)>Click COPY IMAGE ADDRESS
Paste the address into a "NEW MESSAGE" on here.
Check your work with PREVIEW> Re-edit or SUBMIT
.
If all this is too complicated then i'd advise finding a woman.
They're less complicated than computers!
