Hi, I sugguest you using portfolio module.
every logo create a post under some category(assuming is logos)and logo image assigned to post featured image.
with potfolio module settings: ‘Image Ratio’ to ‘1:1(Grid)’ and ‘Category’ to ‘logos’.
I actually had already tried that. They still appear in a masonry format, i.e. appear in columns but not fixed-height rows. Not all the logos are the same height. Is there any way to make them appear in a row (also centered by height)?
