When a user accesses the add item or edit item from the front end. The k2 logo shows up in the top. How would I replace it with my own logo or remove it entirely.

Hy,

use firebug (or similaer), search for css-line, where k2-Logo gets his url, position,… and write "display: none" in that part.

first make overrides, if you dont have.

Regards
