Preview images not rendered in Web > Page view on Windows systems
In Web > Page view the preview images are not rendered on Windows systems. Is is due to failing functions in class TYPO3\CMS\Core\Utility\PathUtility. Basically it's an issue with forward and backward slashes. In the class the constance DIRECTORY_SEPARATOR is used which is on Windows systems a backward slash. Normally paths in TYPO3 are converted to use forward slashes and here is the existing problem.
