beam directory images

hey every1 (:

i got a problem which seems kind of stupid but i cannot get around it...

when i store gobo pallets in the beam directory i cant seem to get an image of the gobo stored. it just stores gobo 1 , gobo 2 ect.

i got to the point where i find these images in the media picker , but i just cant seem to find the way for theme to be stored at the beam directory.

any help will be gr8 (:

thx.
