It would better to just use an array, and then iterate through that.
$images[] = stripslashes( $row['image_1'] );
$images[] = stripslashes( $row['image_2'] );
$images[] = stripslashes( $row['image_3'] );
$images[] = stripslashes( $row['image_4'] );
foreach( $images as $k => $v ) {
$k++; // increment k since it starts at 0, instead of 1
if ( strlen( trim( $v ) ) ) {
echo "<li><a href=\"http://www.theverseoftheday.info/store-images/";
. $v . "\" title=\"Image " . $k . "\">Image " . $k . "</a></li>\r\n";
}
}
