Image not displaying in slider sidebar

Hi There,

I’ve searched for an answer online and even contacted the theme author, but neither of these activities have yielded helpful results : – (

The site I’m administering has a slider that rotates through six images. Each slide consists of the featured image on the left, and a dark grey sidebar on the right. Each sidebar contains text, and most of them have buttons. I’m trying to put an image in the sidebar, but it won’t display on the website itself (it only shows up if I view the slider content in “Post” mode).

Anybody know a way around this? I’m not sure whether it’s specific to the theme I’m using (theme1692) or if it’s a general WordPress kind of question.

Here’s the website:

Apologies if this is posted somewhere else – I’d be happy to use an existing thread – but I haven’t had any luck!

Thanks,

-L.S.
