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"; } } Adam.
