Making a new site but something is happening to it in IE. I've purchased the Nivo Slider for wordpress plugin and it working fine however it's not displaying the thumbnails under the banner in IE.
This is what it looks like in firefox

This is what it looks like in IE

Because this is a plugin (and the website isn't giving me any support after 2 days) I dont really have the source CSS but I was hoping you could take a look at it with come developer tools to see why it might not be showing in IE?
This is what I have found
.theme-default .nivo-controlNav.nivo-thumbs-enabled img {
display: block;
height: auto;
width: auto;
}
Any help or advice is appreciated.
UPDATE

After putting in the new code the .banner-bottom displays on top of the banner on all other pages.
