BP-Scholar Theme embedded Images CSS

Hi,

The Spotlight, News and Scroller have embedded CSS pointing to /wp-content/themes/bp-scholar-child/img/no-attachment.gif'. All of which have different dimensions. It would be nice to be able to control this via CSS. I'm still trying to figure out how to fix, but the only file I can find a reference to "no-attachment.gif" is in "function-image.php".

For the Spoltight:
<span class="attach-post-image" style="height:60px;width:170px;display:block;background:url('http://mydomain.com/wp-content/themes/bp-scholar-child/img/no-attachment.gif') center center repeat">&nbsp;</span>

And the News has
<span class="attach-post-image" style="height:100px;width:100px;display:block;background:url('http://mydomain.com/wp-content/themes/bp-scholar-child/img/no-attachment.gif') center center repeat">

And the Scroller has
<span class="attach-post-image" style="height:60px;width:170px;display:block;background:url('http://mydomain.com/wp-content/themes/bp-scholar-child/img/no-attachment.gif') center center repeat">

Regards,
Larry
