gallery kills my frontpage

hallo everybody
i am using drupal 5.7 and i've just installed the last stable version on gallery2 and gallery module for drupal. everything is ok with gallery pages.
but i want to put some random pictures from my albums to the frontpage and there is my problem.

when i put a imageblock (or grid) my page(which i built with panels) will be inusable. i am sending the screenshots:

this is my page before i add an imageblock

and this is after i add the block
