How to make a gallery in WP so that the thumbnail and large photo are different pictures?

Question

HTML

Good afternoon; A WP site needs to make a photo gallery, click-to-zoom in the Lightbox style, but the problem is that another, third-party photo, individual for each slide, should increase. (to be more specific, there are thumbnails of magazine covers, by clicking on a photo with a spread of the corresponding magazine is enlarged).
How can this be more or less nicely implemented so that there is less code in the admin panel?
did first vlob,

<div class="image_crop"><a href="АДРЕС_БОЛЬШОГО ФОТО" rel="lightbox">
<img class="alignnone size-medium wp-image-455" src="АДРЕС МАЛОГО ФОТО" alt="shop12" 
width="218" height="300" /> </a></div>

but the customer will not bother with this, and it’s stupid to do so.
tell me, what is the mb plugin? Have not found.
