[Theme: PageLines] missing alt text on the quickslider

Hi, I just build my site with pagelines (which is so great , I love it) it all works well except that I can’t find how to put alternative text on the image that I use in the quickslider. I already added alternative text to all my images via the media library but it doesn’t appear on the page.

This is a big accessibility issue and my website will be used by many screen reader users, so I have to gave up that theme if I can’t solve this but I feel there is an easy way to do this.

thanks a lot for your help!
