Accessing image property in IE when there's a period in the html ID?

If an image element has an html ID containing a period, such as for example:
<img src="some.jpg" id="0010.0">

Accessing it's src value in FF and other non-IE browsers may be done by:
alert(document.images["0010.0"].src);

Or if passed as an argument:
function bla(ID){
alert(document.images[ID].src);
}
bla("0010.0");

But neither the above works in IE8 for some reason. I'm not sure about IE9 
and 10 but in IE8 the resulting js-error is:
"document.images.0010.0.src' is null or not an object". 

When containig a period, how can the src (or other) value be accessed in IE?

Many thanks,
Tuxedo
