Value: You can add a static value to the Value field, or you can dynamically display a status, Thumbnail element content or the value of an action result via Symbol Picker.
Placeholder Image: Placeholder is the image shown when there is no Image value. If no content is loaded, the user will be shown this image instead of an empty space.
Zoom On Click: The Zoom On Click property determines whether clicking on thumbnails will display a larger version of the image. When you activate the switch, you can switch from a small preview to a full-size image.
Image Fit: The Thumbnail element can have a custom size based on the dimensions specified in the Styling > Layout tab, or it can be scaled to the dimensions of the parent element. In this case, you can specify how the image to be displayed fits into the Thumbnail frame.
Position: You can determine the position of the image to be displayed in the Thumbnail element by selecting it from the drop-down menu (bottom, center, right, left, top).
