Re Mixing stereo tracks to mono in your Project I had to change the image layout from how you left it as if you don't have tables you must use <br clear="all" /> at the end of the text related to the image. This is what your edit looked like with smaller font size in IE:
I never really know if you are writing a step by step guide if images should go underneath rather than to right as is otherwise received wisdom. Personally I think left looks better if the text goes below the image line - visual studies suggest the eyes tend to focus from top left to bottom right. Anyway I made the images on the right now. I was trying to stop too much white space around the dropdown image if the user had very small text size but I agree the last solution looked a little odd.
