The white space is not allowed in urls, you need to replace it with %20 url中不允许有空格，需要用%20替换
As soon as I remove the spaces I try to replace them by hyphens or %20 as recommended by some online I get even more errors
well the W3C validation service will complain about the absence of doctype declaration and the title element and the lang attribute W3C 验证服务会抱怨缺少doctype声明以及title元素和lang属性

<!DOCTYPE html>
<html lang="en-us">
<head>
<title>Some title</title>
</head>
<body>
<img src="webpage%20photos/alcazar.jpg" alt="Alcazar Palace">

The value of src includes a space which is not allowed as legal value. src的值包含一个不允许作为合法值的空格。 please move out the image to another place without any space in path, and re-link to it again.请将图像移到另一个位置，路径中没有任何空格，然后重新链接到它。

You could use the PHP function str_replace() to replace the spaces with %20.您可以使用 PHP function str_replace()将空格替换为 %20。
But you likely be better off using the PHP function rawurlencode() as it will encode anything else that should also be encoded.但是你可能最好使用 PHP function rawurlencode()因为它会编码任何其他也应该被编码的东西。
Use rawurlencode() on the base name of the file name, or in your case, each directory name.在文件名的基本名称上使用rawurlencode() ，或者在您的情况下，每个目录名称。 This will transform spaces to %20, among other things.这会将空格转换为 %20 等。
You don't want to include the directory seporators '/' in the call to rawurlencode() as they will also get transformed and not work correctly.您不想在对rawurlencode()的调用中包含目录分隔符“/”，因为它们也会被转换并且无法正常工作。
