WP caption image floating

The default WP inserting image allows for captions and alignment. But it does not seem possible to insert more than one image on a single line. Example: display: inline. When I insert the images they are in a column down the left or right. I want to be able to do float: left or float: right. Here is some of my code:

[caption id="attachment_963" align="alignnone" width="150" caption="Tricia Spayer"]<img class="size-full wp-image-963 " title="Tricia Spayer" src="http://notebook.stc.org/wp-content/uploads/2010/01/tricia-spayer.jpg" alt="Tricia Spayer" width="150" height="150" />[/caption]

[caption id="attachment_957" align="alignnone" width="150" caption="W.C. Wiese"]<img class="size-full wp-image-957 " title="W.C. Wiese" src="http://notebook.stc.org/wp-content/uploads/2010/01/wc-wiese.jpg" alt="W.C. Wiese" width="150" height="150" />[/caption]
