<?php
$images = glob("{small/*.jpg,*.bmp,*.gif,*.png,*.jpeg}",GLOB_BRACE);
$images_big = glob("{400/*.jpg,*.bmp,*.gif,*.png,*.jpeg}",GLOB_BRACE);?>
<?php foreach (array_combine($images, $images_big) as $image => $image_big): ?>
  <div class="img_item"><img class="slider_img" src="<?php echo $image; ?>" alt=""></div>
  <div class="img_item"><img class="slider_img" src="<?php echo $image_big; ?>" alt=""></div>
