Hi Sarah, to add an image on the left of a menuline just put your image as HTML in the line definition:

<div id="mimic" class="voice {action:'ui/arms.ui.parts/genericContainer.html'}"><img src="ui/arms.ui.images/icons/icons_basic/clock_16.png" alt="icon"/><span class="txt">Mimic (form)</span> </div>.

If you need an example I'm working on a application GUI made with some of my components; you can find a preview at this URL: http://www.open-lab.com/arms/index.html.

For the possibility to add images rather than text into the extruder flap there's not a specific method yet (next release surely). but I think you can do it via CSS changing the .extruder.top .flap class and setting the image as background of the flap:

.extruder.top .flap{
  color:white;
  text-shadow: #000 2px 2px 2px;
  font:18px/18px Arial, Helvetica, sans-serif;
  text-align:center;
  display:block;
  padding:0 5px 5px 5px;
  height:30px;
  background:url("../elements/[your flap image].png") no-repeat top center;
  cursor:pointer;
}

Hope this can help you, Bye, Matteo
