Thanks you both for answer.
I think that Brenden's solution will work. I'll try it tomorrow - here is late night.
I used this manual, but there is no trasformation.
Below are some images of settings.
Form. Multiple images of one product.
Part of transformation
<div class="product-img-area flex-container vertical-center">
<img src="<%# GetAttachmentUrl(Eval("PoolImage"), Eval("NodeAliasPath")) %>" alt="SwingPools">
Result. Multiple product with (expected result) first image show.
