Blocks

Hi all,

I recently installed the Quote_of_the_day Block in my Moodle 1.6 and "misused" it as Random-images + copyrightinfo viewer.
It works great and simple. Not hacking was needed.
But when the site is reloaded moodle doesn´t want to show the german umlauts anymore. But if you switch the quote block off, the umlauts are back again. Really strange.. have no clue how to solve this issue.
Please find the source of the block below.
Any ideas are warmly welcomed.
Thanks guys.
