Hi. I've replaced the default Gantry banner image with my own banner image, tho it is not showing up correectly. See here, the partial image in the upper-left corner, should be much larger, and it needs to be re-positioned:
I do not understand why this is happening or how to make modifications to the banner area. And I've not been able to find a comprehensive tutorial on how to manage the banner image. Anyone know of a good tutorial for this specifically? Or can tell me to how to make such modifications?
