Is the image on your Homepage next to About Us not fitting properly, like this one?
This may be because the image is adaptive/dynamic to the text box next to it! If you want the image to be taller, you will need to add more text. This can be done here; in the 'Small description' box.
The image is your Business Profile Image, which you can change here.
You can see with the one above, because there is little text in the description, the image is getting cut off.
Now we've added a lot more text, the image can be displayed more clearly.
