Answer 1

If You want all images from one restaurant. Your Image Function should return all images and return it.
Maybe the whole img Tag.
function getimage($catid) {
$image="select * from `restimage` where `res_id`='$catid' ";
$imageresult=mysql_query($image) or die(mysql_error()) ;
$images = array();
while($row=mysql_fetch_assoc($imageresult)){
$images[] = '<img src="image/'. $row['rest_image'] .'" width="100" height="100" />';
}
return implode('', $images);
}
