Need help creating space around images in posts (Wordpress)

Hi, in a theme im using, when i insert an image into the post theres no space around the image, im not sure what to edit in the CSS file as ive not created this theme myself, if anyone can advise please.

With no space around images the text in the post currently touches the edge of the inserted image.

Heres the CSS:

* {
	margin: 0;
	padding: 0;
	border:none;
}
body {
	background:#dcfaff;
 	font: 62.5% "Trebuchet MS", Verdana, Arial;
}
/* Links -----------------------------------------------------------------------*/

a {
	color: #0d6b93;
	text-decoration: none;
	outline:none;
}
a:hover {
	color: #333;
}
ul {
	list-style:none;
}
.clear {
	clear:both;
}
.alignleft {
	float:left;
}
.alignright {
	float:right;
}
.imgleft {
	float:left;
	margin:0 12px 12px 0;
	border:4px solid #bcd4de;
}
.imgright {
