On the invitation itself, text sits beside, above or below the photo, on the card colour. Only two of the social media images put the text over the photo.
Here readability comes down to two colours: your text and the Card. A dark card needs light text, and the other way round. How to choose those colours is explained in Choosing the background and card colour.
In Vertical (style 3) and Portrait (style 2), the photo fills the whole image and the text sits on it, white by default. A dark gradient at the top and bottom darkens the photo there a little, so the text stands out. That gradient is fixed: there’s no slider to darken the photo yourself.
More about the formats and adjusting them in The images for social media.
