+	  <p>Thanks to MORI Shingo of DeNA Co., Ltd. for reporting this.</p>
+	  <p>There is an issue where if an HTML file is uploaded with a .html
+	    extension, but the content type is listed as being `image/jpeg`,
+	    this will bypass a validation checking for images. But it will also
+	    pass the spoof check, because a file named .html and containing
+	    actual HTML passes the spoof check.</p>
+	  <p>This change makes it so that we also check the supplied content
+	    type. So even if the file contains HTML and ends with .html, it
+	    doesn't match the content type of `image/jpeg` and so it fails.</p>
