Reducing Map Tour icon size?

[sdctchair]

I have created several Map Tours in my Story Map.  I am using the Explorer layout (with either grid or list view), and have added a picture/icon for each case study. I would like to make these pictures smaller in size. Is that possible? 

Best, 

Joanna

@sdctchair -- Thanks for posting your question about map tour images. Could you please share a screenshot of the view in which you'd like to reduce the size of the images and describe a little more about what your expectation is? I'm not quite sure where or how you mean for this to happen.
