Icon sizes in 'recently added businesses' widget

Hi

I have a recent custom posts type widget running in the right hand side of my site Link removed at members request which is called 'Recently added businesses'.

I had a lot of help from Jack with getting the image sizes reduced, but then I had to change my theme and now the image sizes are too small! (sorry Jack!)

Can someone tell me where I can find the code I should be adjusting to bring the images back up to a larger size please?

Is it somewhere within my simple custom css plugin (code shown below) or should I be looking somewhere else?

div.cf-info, div.entry-meta { margin: 0; width: 100%; }
div.entry-meta { width: 97%; }
div.cf-ad div.cf-info { width: 74%; float: right; }

.dr_taxonomydiv{
	float: left;
	display: block;
	width: 100%
}

#status-box {
	display: none;
}

#footer #menu-footer-bar-menu li a {color:#ffffff; float:left; margin:2px 10px; padding:2px 5px;}
#footer #menu-footer-bar-menu li a:hover {background:#000000;}
#footer .fleft {clear:both;}

body {padding-top: 0;}

span.rcpt_item_image {
height: auto !important;
width: 10px !important;
} :)
ul.rcpt_items_list li span {
display: block;
font-weight: bold; font-size: 1.2em;
} :)
span.rcpt_item_title {
display: block;
font-size: 1.4em;
font-weight: bold;
}

ul.rcpt_items_list li span {
    display: block;
    font-size: 1.2em !important;
}
.post-content .single_job_listing .company { display: none }

div#register-page.page {width : 94% !important}

Thanks

Sally
