I’ll see what’s happening with the FTP, but just doing a quick search on the CSS the height is being forced, see the CSS Path
#product-1470 > div.row > div > div.row > div.col-lg-6.col-md-6.col-sm-12.product-images > div.images > div.product-images-slider.main-images.images-popups-gallery.zoom-enabled.owl-carousel.owl-theme > div.owl-wrapper-outer.autoHeight
On all images this is first seen as around 330px high but can vary, until you rotate the images then it goes to the correct height
