Can't get thumbnail aligned top-left

I’m a newbie. Trying to get the image in the top-left corner of each div, with the title, date and excerpt next to it separated by a line break each.

I’d also like each listing to be separated by a few spaces. Any help?

Here’s my CSS:

img.lcp_catlist { float:left; margin:5px 10px 5px 0; width:100px; height:100px; vertical-align:text-top; }

span.lcp_title {
display: block;
font-size: 11pt;
font-family: sans-serif;
}
span.lcp_excerpt {
display: block;
font-family: sans-serif;
}
.lcp_date p {
display: block;
}
#content ul.lcp_catlist li {list-style-type:none; display:block;}
ul.lcp_catlist li {list-style-type:none;}

And here’s my shortcode:
[catlist id=”12″ numberposts=”15″ orderby=”date” date=”yes” excerpt=”yes” excerpt_size=”50″ template=”default” thumbnail=”yes” thumbnail_class=”lcp_catlist” date_tag=”span” date_class=”lcp_date” excerpt_tag=”span” excerpt_class=”lcp_excerpt” title_tag=”span” title_class=”lcp_title”]
