[ When your playing with your codes, in whichever way that you do, take note that an 'innerHTML="<bla,bla,bla..... ' dose not like blank spaces in-between the words that make up the name of a file or page that it calls, so 'an image.jpg' or 'my web page.htm' will not be reacted to, well my page doesn’t any way.
I read somewhere that any names you make up for your divs, functions, forms etc should be joined together with a capital letter to denote the beginning of the second word, like 'aFunc6' or 'meBigBot' or whatever. Having recited this for you here I must still say that, after having created an amazing CSS file with all kinds of groovy names and calls I saved it in a CSS editor that automatically changed them all back to small letters, it didn’t put spaces in them though, so that fact remains. ]
