I'm using the simple NG theme. I'm a beginner when it comes to this stuff.  What I want to do is on the home page of my site I want to make the thumbnails for the different album categories larger. If anyone could at least tell me the file that I would need to edit I would be very grateful.

There are a few other things I would like to know how to do, one would be to remove the breadcrumb "home" on the first page.

I also want to get rid of the text that says how many images are in an album when you mouse over the thumbnail.

thanks so much
