W3C Validation Failed, llegal character in path segment: space is not allowed, Even though there are no spaces

Hello I am trying to figure out why is it telling me that the spaces is not allowed even thought from the HTML you can see that there is no spaces in the img

 <img src="media/Review 1.jpg" alt="Review" class="Reviewphoto">

Thanks for your help in advance!

Answer 1

The space is right there, between Review and 1 :

 <img src="media/Review█1.jpg" alt="Review" class="Reviewphoto">
                       ^ here is the space

Do you see it now?

You need to encode it as %20 so the URL becomes media/Review%201.jpg :

 <img src="media/Review%201.jpg" alt="Review" class="Reviewphoto">
