I think adding

.alignleft {
    float: left;
}

to your stylesheet should do it.

Put a

border: 0;

in the image class that you want to have no border, or create a new class for images without any borders. If that doesn’t do it, make sure to get all your classes in. For example, if you have

<div id="content">
<div class="post">
<img src="url" class="class" />

</div>
</div>

then you’ll need to specify in your stylesheet

#content .post img {
    border: 0;
}
