[WSG] Linking Background Images

[CriddyMail]

Greetings,

I have two questions please.

1. Is there a way to link background images? I want to link my banner image, which is currently set as a div background image, back to the homepage .

2. Can I specify image sizes within my css definition? Here are two scenarios:
      
       a. background image - #contentWrapper{background:#fff url(images/banner_whole_2.jpg) repeat-x;}
      
       b. html source: <img src="" width="96px" height="32px"  alt="Picture" /> (Assume that I want all images to display in these dimensions.

Thanks so much for your help.
Mary
