Protect img for google

If I create a folder on the server with pictures, I would like to load them ONLY for users with the correct password.

in short:

the user enters the password and then we use Ajax to load the image as img src syntax into the HTML file.

I realize that the direct image call is also possible without a password. However, the pictures are in very unusual folder paths.

what I'm interested in:

if Google or any other search engine crawls / indexes my page, will these images also be inserted and could appear in Google Image Search? reply
