I don't know if I can be much help at this point. Sorry!
Once way to not use the iframe at all is to put in the image slideshow code directly into the page. Not sure if this will help you or not.
To do this there is a little utility on our websites: http://docs.sencha.com/animator/help...rtUtility.html
Note that this only works with projects that have one scene and the utility itself is very untested.
