OK, I found the problem. CSS should be
.tthumbimg, .tthumbPreview {
opacity: 0.5 !important;
}
.ipsDataItem_unread .tthumbimg, .ipsDataItem_unread .tthumbPreview {
opacity: 1 !important;
}
@Lenny Warren The padding issue will be fixed in the next version.
I will not update this feature because there are some people who don't like the lighter thumbnails. But you can do it by going ACP > Customization > Themes > click </> to edit your theme > CSS > core > custom > custom.css
Add this code
.tthumbimg {
opacity: 0.5 !important;
}
.ipsDataItem_unread .tthumbimg {
opacity: 1 !important;
}
Save
The next version will support Topic Thumbnail Currently, if you it pulls the first image in topic if you select getting contents from Forums. In 'No auto' mode, you can use custom images, titles, urls.
It also supports Pinned, Featured Topics.
