### Media
#### Aspect ratio
Choose how images are displayed within your blog cards.
Available options include:
* **Auto:** Automatically adjusts to the image’s original dimensions.
* **Square (1:1):** Keeps all blog images in a perfect square shape.
* **Portrait (4:5 / 3:4):** Ideal for vertically oriented images.
* **Landscape (16:9 / 4:3):** Best for wide, horizontal images.

#### Corner radius
Use the slider or input a pixel value to adjust the roundness of image corners (0 - 32px).
A higher value results in smoother, more rounded edges, great for a modern, friendly look.
