How can I remove hero portraits in-game?

Hello,
i was wondering if there is any way to remove the hero portraits from the in-game screen (the portraits that show up in the upper left corner)?
Help would be appreciated
greetings

I finally found it, thanx for your help, functions perfectly

still have no clue how i could scroll over this again and again without noticing, must have been really tired that time...

well thanks again
