Text boxes have a special function wherein you can upload images inside of the text box. You can either click the image button on the menu, or manually paste an image (if you're on a PC/Mac).
To manually paste an image, simply press "PrtScSysRq" or Print Screen System Require, and then press CTRL + V.
All images uploaded in a text box also have an option to be cropped, which is discussed in the next topic, Image Cropping.
Summernote is a very widely used JS Rich Text Editor, and that is what we are using for this text box. It cannot be overstated how well-programmed it is.
