Hi, if you are using Mosaic effect for the category view and you have some margin/padding between photos, you need to resize the image so it is the same height like two images (two images + padding/margin = one image height)
See parameter: Margin (Additional Thumbnails)
(Thumbnails must be recreated after setting the parameter - so the thumbnails will have new height)
Names: you can display names everywhere and then hide them per CSS for the part of website where exactly do you need to hide it.
