for now you can create inline elements.
create your image frame and fill it, copy it, go into edit mode of the text frame, paste.
now the image is treated as a glyph.
warning: in 1.4 you can't edit the picture that you pasted, so keep the original somewhere.
a better way to link elements together is being worked on by cezary and may get into 1.5!
