Hello Zen Forum....my first post, and question....

Love the forum, it has been some great help....

However I can not figure this one out, and have not been able to find anything on/or close to the subject....

In my pages title across the top, I would like to do logo, title text, and another pic....
[your logo here] [title text] [pic of our REAL store]
instead of the default [your logo] [title text]

the image would be almost the same size as the logo image....
where would I modify the css, ie: which css, in which folder, and what tag.....

(ps: I have a decent understanding of Zen, and custom templates, the proper way to create directories, and copying over the files that you are changing)
(pss: and a very novice grasp of css, but getting there)
