All--
Bret's observation regarding keeping the picture board up-to-date is extremely important--for all informational things you have distributed or displayed. It simply adds to the frustration students are feeling when they are in need of interacting with someone.
It doesn't hurt to change it up once in awhile as well. Rearrange the pictures, put up a new background, etc. Students will stop and look at it with 'new eyes' even though the same material is there.
