A few setup questions

Sorry about the trouble with the ‘Show link name when no image is assigned’ option. There was a big in it. I just pushed out an update to correct the issue.

As for your styling issues, can you give me a link to your site so I can see the library in action? There may very well be a conflict between Link Library’s styles and what is defined in your site’s theme.

Add the following CSS rule to the Link Library stylesheet editor:

table.linklisttable td img {
    vertical-align: middle;
}

This should take care of centering the images in your cells. It did when I tested on your site using the Chrome Developer Tools.

Let me know if this is now displayed as desired.

If you wanted to set the row height, you would need to add a class to the <tr> tag at the beginning of each row, so it would look something like this:

<tr class="linkrow">

Then, you could add a style in your stylesheet to target that specific row:

.linkrow {
     height: 100px;
}

As for your column width issue, it can be resolved in a similar fashion by adding a class tag to the <td> HTML tags for both the image and link name fields, like this:

<td class="linkfirstcell">

Them, adding an entry to the stylesheet editor to make these cells a certain width:

.linkfirstcell{
     width: 150px;
}

Of course, adjust the width and height values based on your layout.
