How do I have the title to the right of the image

In your custom emplate – see the Template System instruction here: https://www.ads-software.com/plugins/list-category-posts/other_notes/ –
or in your default template
\wp-content\plugins\list-category-posts\templates\default.php

you must move this

//Post Thumbnail
  $lcp_display_output .= $this->get_thumbnail($single);

before this

//Show the title and link to the post:
  $lcp_display_output .= $this->get_post_title($single);

and then in the css of your theme you must add this:

.lcp_catlist img {
float: left;
margin-right:10px;
}

or this if you want also resize the thumbnails (for example 100×100):

.lcp_catlist img {
float: left;
margin-right:10px;
width:100px !important;
height:100px !important;
min-width:1% !important;
}
