A stray double quote ended up inside the `width` value of an `<img>`, usually because the opening quote is missing (`width=200"`) or the quotes don't match (`width='200"'`).

The `width` attribute takes a non-negative integer: digits only, with no quotes, units or spaces. Without an opening quote, the browser reads the value as unquoted, which runs until the next space or `>`, so the closing `"` becomes part of the value. The validator reports this case twice, once with this message and once as `“"” in an unquoted attribute value`. When the value opens with a single quote and closes with a double quote, it runs until the next single quote, and the `"` again lands inside it.

Browsers parse `width` leniently and read `200"` as `200`, so the image often looks fine. A value that starts with the quote, such as `"200"`, fails to parse, and the browser ignores it. The image then gets no reserved space before it loads, and the content below it shifts once it arrives.

Templates and string-built HTML cause most of these, for example `width=<%= width %>"` with the opening quote left out. Put matching double quotes around the number.
