Make sure these two lines are correct in showflat.php
<br /> $TempBod .= "<br /><br /><IMG SRC=\"$config[fileurl]/$File\" width=\"{$config['max_width']}\" Border=\"0\" alt=\"{$ubbt_lang['FILE_ATTACH']}\">";<br /> }<br /> else {<br /> $TempBod .= "<br /><br /><IMG SRC=\"$config[fileurl]/$File\" Border=\"0\" alt=\"{$ubbt_lang['FILE_ATTACH']}\">";<br />
Looking at your HTML, I am guessing that they are not as the width is not shown at all in your HTML code. So also make sure the width variable is set in the config.
