'Resources/Public/images/my_image.jpg'; echo "The image URL is: $imageUrl";This code retrieves the path to a folder containing images for the "my_extension" extension, then uses `t3lib_extMgm::siteRelPath` to get the site folder's relative path, and finally concatenates the paths to create a URL to an image file. The URL can be used to display the image in a webpage. The php t3lib_extMgm library is included in the TYPO3 CMS package.
