embedded image display error on “page”

For some reason, our site is not “processing” an embedded image correctly.

For example, at the bottom of the page

“https://www.louisvilleart.org/wordpress/who.html”

WordPress has somehow inserted tags into our original text which is messing up the rendering of the images. This happens on all images we've uploaded and embedded.

In the "Manages -> Pages" editor, using the editor to drop an image and then "right align" it, the original html looks like this (I've changed all less thans to left brackets and greater thans to right brackets for this example):

[hr /][img align="right" id="image22" alt="SCFD Logo" src="https://www.louisvilleart.org/wordpress/wp-content/uploads/2006/08/scfdlogo1.thumbnail.jpg" /]The LAA is partially funded by the Scientific and Cultural Funding District (SCFD), which receives its funding from state taxes.

But when you “View Source” in the rendered html page it looks more like this (both in the preview section of the editor and looking at the normal website):

[p][hr /][img align[code]"right" alt[/code]“SCFD Logo” id[code]"image22" src[/code]“https://www.louisvilleart.org/wordpress/wp-content/uploads/2006/08/scfdlogo1.thumbnail.jpg” /]The LAA is partially funded by the Scientific and Cultural Funding District (SCFD), which receives its funding from state taxes.[/p]

Any idea where these [code] tags are coming from?

Thanks (in advance) for any tips or direction in hunting this one down.
