You should be able to use an override template. Simply add the appropriate eZ code to your template to display the image instead of, or in addition to the text.
An example of how to display the image would be to use: {attribute_view_gui attribute=$content_version.data_map.image image_class=large}
Assuming the field in your class is titled "image". If it is something else change data_map.image to data_map.the_proper_field_name.

<object id="id"[ align="left|right|center" size="small|medium|large" class="foo" view="embed|text_linked" href="link url" target="_self|_blank"]/> where 'id' should be an existing eZ object id and all other attributes are optional. Attributes 'href' and 'target' are used to make object(image) as link.
