The image elements of materials can be either fixed or editable.

Often the placement and sizing of image elements, such as logos, is determined by the style guide used, in which case they cannot be edited.

You can identify editable image elements by the icon displayed in the element menu.

In the working area, you can identify an editable image element by the icon that appears in the upper right-hand corner of the element and the icon that appears on top of the element when you click on the element.
