The picture just below the title "Tizio Micro" looking down on the lamp with the lawn behind, part of the collage of five photos, has been squished horizontally or stretched vertically quite a lot. Many of the other photos on the page have also been stretched in one direction but not the other.
Oh those, are vertically shot ones! They are not thinned. Their composition are like that. When you press/click on them you should be able to see them in full page. They look nice on the phone, but on your desktop/ipad (depending on the orientation) it might look bad yeah.
