Is there a way to resize the school logo so that it appears larger on the homepage. I am using the professional template and the logo seems so small in the space that it occupies. It would look better if it were larger.

Because of the template you are using, the image must be smaller. If you choose a different template, the image is a little bit larger.

Well, I was using the 70's template and then the school photo was getting cut off so I switched to the professional which you suggested to fix that problem. I think the template should make the image fit to the space it allows (the white area). I even tried saving the photo in a larger size and reloading it, but that didn't help at all. So there is no way to set a size for the photo? Is everyone's photo using that template too small for the space?

The logo size as displayed is a fixed part of the template, and is the same for all users of the template. We are working on adding a new template system with greater flexibility, but in the meantime the only thing you can do is remove as much as possible of the empty space surrounding the logo in the original image.
