slideshow thumbnails loading slow (shows text first)

Hi,

i have a question about Brine template. On my landing page i have several slideshows and it takes several seconds to load all the thumbnails.

I'm ok with that, just brine template is showing a name of the images or icon of broken image before it loads. No other template does this, just all brine family templates. Other templates simply show blank white space until image fully loads. 

Functionally its all OK, it just aesthetically doesn't look good to see the image names for couple of seconds.

Any ideas how to fix this?

Thank you
