Category Icons and Suffusion

I am having a world of trouble getting my category icons to appear where I expect and in the correct size.

Can someone point me to a reference or just explain where I should be seeing the large icons, where I should be seeing the small icon, and where I should be seeing no icons at all.

I am using Category Icons v 2.2.1 and Suffusion v4.2.8. I am working mainly with the Magazine template.

Thanks in advance for any help provided! ??
