    This seems relatively tricky.

    One way would be to use the Caption or Description meta box in the Image Uploader to store a class name, and then output it like this

    <img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" class="<?php echo $image['caption']; ?>"/>

    Or you could output a generic class for all images

    <img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" class="gallery_images_class"/>

    and then use a css :nth-of-type selector to target specific instances (eg. images 4, 7 out of 10)
