The Image field enables choosing a file from the device you are using and uploading it to be stored and associated with the content. The maximum size of the file is given below the field (typically 2 MB) and so are the file types that will be accepted. I'm going to add an image and enter Sasha and her donut as alt text. Alt text is used to provide information about the image to those users using a screen reader or some other form of access rather than viewing the image.
INLINE images versus ATTACHMENT images:
Images that are inserted into the text by way of the WYSIWYG editor are treated as part of the text, while images attached to the content by way of the image upload dialog are considered an independent part of the content, like the title, and their visibility can be configured for various contexts, such as teasers, RSS feeds, and so on.
