Image ratio problem and no carousel

I noticed it happens when the image gallery is more narrow than its container, for example add just 2 pictures in a 2 column layout.

Hi drupaldope, EPT Image gallery doesn't have carousel functional, here are few EPT modules for carousel/slide images:

https://www.drupal.org/project/ept_slick_slider →
https://www.drupal.org/project/ept_slideshow →

Maybe you mean slideshow in lightbox popup, I think it was fixed for Glightbox integration module:

There are new options for selection gallery for field, paragraph or for entire page:

/admin/structure/media/manage/image/display/ept_image_gallery - EPT Image Gallery

/admin/structure/media/manage/image/display/ebt_image_gallery - EBT Image Gallery

About wrong ratio when first row is not full of images:

It's possible to select Style 2 Columns for gallery where is small number of images. But for the case for 2+ columns and only two columns, I fixed CSS:

I pushed updates in new release:
