Change Box Corner Graphics

/includes/boxes/eachfile
Take a look into the code of each box. There you'll find something like this:
new infoBoxHeading($info_box_contents, false, false);
 
If you set both from 'false' to 'true' your box will get rounded corners on the left and right site
 
BOX CORNER CHANGES ON SEARCH BOX & NEW PRODUCTS BOX:
/catalog/includes/classes/boxes.php
Change about line 101
if ($left_corner) {$left_corner = tep_image(DIR_WS_IMAGES . 'infobox/corner_left.gif');
 
To
 
if ($left_corner) {$left_corner = tep_image(DIR_WS_IMAGES . 'infobox/corner_right_left.gif');
 
This will only change the left corner of the search box.
 
Change infobox/corner_right.gif  at about line 111. This will override all the boxes to have square corners regardless of what settings the boxes files are set to.
 
if ($right_corner) {$right_corner = $right_arrow . tep_image(DIR_WS_IMAGES . 'infobox/corner_right.gif');
} else {
 
TO:
 
infobox/corner_right_left.gif
 
LINE 147 CHANGE TO MAKE THE "NEW PRODUCTS" BOX HAVE SQUARE CORNER ON THE LEFT SIDE:
 
$info_box_contents[] = array(array('params' => 'height="14" class="infoBoxHeading"', 'text' => tep_image(DIR_WS_IMAGES . 'infobox/corner_right_left.gif')),
array('params' => 'height="14" class="infoBoxHeading" width="100%"', 'text' => $contents[0]['text']),
