Promo Screenshow Problems

Hi All, I recently created my first Dolphin 7 site, sometime during the customisation i managed to do two things, 1 the promo screenshow images have become out of line ( for guests only, those on the members homepages are still correct, any ideas where I should look? secondly i managed to delete the standard penguins/dolphin promo images trying to sort the first problemanyone help identifying them in the core package so i can reload them?

First the empty sign appeared in the forums. They are not empty by the way now the this page is messed up http://livingdistracted.com/forum/
