Various extensions modify and build upon default TYPO3 behavior (as we have seen already). In this recipe, we will make use of the rgmediaimages extension to add videos to the Text with image content element. This is a classic example of extending default TYPO3 behavior and adding more functionality to the system.
We assume you have already installed the rgmediaimages extension. If not, use the information in the Chapter 1 recipe Installing needed extensions to install it now.
