Google Image search weird issue

Im trying to do a google search by image url using this link, it works for most websites(?), but not all

window.open("https://www.google.com/searchbyimage?image_url=" + image_url), 'popUpGoogle', 'height=400, width=600, left=10, top=1');

Here’s the issue, lets take this picture for example https://vladimirkhil.com/siserver/3/packages/0t%2BefNNidBXgG1am3LaK5nczmak%3D_kLhfz3q9duZyqOT%27x9qDZw%3D%3D/Images/quake.jpg

the link would be

https://www.google.com/searchbyimage?image_url=https://vladimirkhil.com/siserver/3/packages/0t%2BefNNidBXgG1am3LaK5nczmak%3D_kLhfz3q9duZyqOT%27x9qDZw%3D%3D/Images/quake.jpg

But when I open it I get :

The URL doesn’t refer to an image or the image is not publicly accessible.

However, if I open the image in a new tab, and then do a google search manually by right clicking it works, but whats more weird is that it also works if I go to a “Search by Image” on google and past the exact same image link there

Any ideas what this could be related to? The URL clearly refers to an image and it is publicly accessible, is it something with the URL encoding? It looks fine to me, also it works in 2nd method that I described so I’m really lost

Answer

You have to encode the url if you pass it as argument to another url.

Your base url is:
https://www.google.com/searchbyimage?image_url=

Your argument url is https://vladimirkhil.com/siserver/3/packages/0t%2BefNNidBXgG1am3LaK5nczmak%3D_kLhfz3q9duZyqOT%27x9qDZw%3D%3D/Images/quake.jpg

Your encoded (encodeURI, escapes ‘%’ signs) argument url is
https://vladimirkhil.com/siserver/3/packages/0t%252BefNNidBXgG1am3LaK5nczmak%253D_kLhfz3q9duZyqOT%2527x9qDZw%253D%253D/Images/quake.jpg

Your encoded (encodeURIComponent, escapes ‘%’ and ‘/’ in your case) argument url is
https%3A%2F%2Fvladimirkhil.com%2Fsiserver%2F3%2Fpackages%2F0t%252BefNNidBXgG1am3LaK5nczmak%253D_kLhfz3q9duZyqOT%2527x9qDZw%253D%253D%2FImages%2Fquake.jpg

To actually do the encode call the javascript function encodeURI MDN with the url to encode. The encoding process will escape chars that have a special function in urls (like the % sign in your case)

Your final search url should look like this https://www.google.com/searchbyimage?image_url=https://vladimirkhil.com/siserver/3/packages/0t%252BefNNidBXgG1am3LaK5nczmak%253D_kLhfz3q9duZyqOT%2527x9qDZw%253D%253D/Images/quake.jpg

Tested. And worked. At least for me 🙂

EDIT:
Might be a better option to use encodeURIComponent MDN over encodeURI
