Responsiveness in Sparks

Hi,

I've installed the Sparks theme which works perfectly.
Now, I've changed the pictures for the Hot Full Carousel. That also works when you are looking at the site ( www.surinamedag.com/symposium_sparks ) on a regular browser on your computer.




However, when you resize the browser or look at the site via a mobile device the pictures aren't showing.




I've made sure that I have the same resolution as the original examples (1600x600 for the full size pictures and 800x600 for the small size pictures) and I've made sure to add the "small_" text before the name of the full-pictures. Again similar to the examples (woman1.jpg and small_woman1.jpg).
Still, I don't see the pictures on the mobile device.

Do you have any suggestion as to how to solve this?

You have mobile optimization on. So your default image is:

for smaller resolutions you need :
