You can create multiple libraries by going to the General Options section of Link Library and increasing the number of libraries to be higher than 1. Once you have more than one library, you can select the one to display in the shortcode with the settings option [link-library settings=”1″]. The main reason for the include and exclude override in the shortcode is if you want multiple pages to have the same layout, but different categories. But you can also achieve the same result with multiple libraries, configured to show different categories. The main thing to keep in mind is that if you make copies of a libraries, and configure each to show one or more categories, you will need to update all of them if you want to change something about the way they display things.
You need to understand CSS to be able to make changes to the layout. The entire library gets a class called linklist assigned to it. So for example, to get the text displayed to the right of the image, you could add the following rule at the end of the stylesheet editor for Link Library:
.linklist img {
float: left;
padding-right: 30px;
}
As for the underline question, are you talking about the short blue line in the bottom-left corner of the image? I downloaded the image and that underline is actually part of the image file. Edit the image and re-upload it and you should be fine.
