HTML img tags can only have one src attribute, and only one value for that attribute, i.e. only one image.

There is the new srcset attribute that can allow different versions of an image (mainly used for 'responsive images'), but browser support is... not great.

Otherwise you might have to change the entire thing to use a different element, such as a div, and then you can actually use multiple backgrounds with CSS.

Treehouse has a quick tip video on how to achieve that with CSS: Multiple Background Images with CSS
