Hi! I am working in Debut theme and looking to have a large photo when one is entering my store. I'd love if this photo could click out to a link without adding a button. However, if I do need to add a button, how can I move the button so that it is not in the center of the photo? 

Additionally, the photo is changing size when switching to a mobile view which is cutting off the text in my photo.
