+This module defines a tree image widget, to be used with function fields of
+type character. Use widget='tree_image' in your view definition. Optionally, set
+a 'height' tag. Default height is 16px.
+
+The content of the field can be any of the following:
+
+* the absolute or relative location of an image. For example, \
+"/<module>/static/src/img/youricon.png"
+
+* a standard icon from the web distribution, without path or extension, For \
+example, 'gtk-open'
+
+* A dynamic image in a data url base 64 format. To show a regular image field \
+from the model, use a function field wrapper that retrieves the image with \
+bin_size=False in the context, and prefix with 'data:image/png;base64,'
