Looking for a plugin that changes image sources with key presses

I'm trying to have multiple images that would show up when I press specific keys, as an example when I press A a blue circle shows up and when I press W a red square pops up, and if I press A and W they both pop up. I've found this plugin that does almost exactly what I want, however it doesn't support multiple images showing up at once, so if I press A then W while still pressing A, the blue circle would disappear. Are there any plugins that can do this?
