wersja skryptu MyBB: 1.6.15
adres forum: ayseinowi.ct8.pl
na czym polega problem (screen, opis, komunikaty, nazwa stylu/theme/szablonu): Jak zrobić efekt trzęsiania sie loga po najechaniu na niego tak jak na tym forum? - gt-advert.xaa.pl

Mam 2 myśli jak to zrobić ale nie jestem pewny.

Np. http://104bajery.vgh.pl/viewpage.php?page_id=28

I gdzie ten kod wkleić?

<style>
.shakeimage{
position:relative
}
</style>
<script language="JavaScript1.2">
