Can't write to temporary download target directory

Hi, is there anybody who can tell me where in konquorer I can change the default temporary download directory? When I f.e. go onto "http://www.amazon.de/exec/obidos/ASIN/3608958177/028-8254727-6130121" and click onto the link called "Größeres Bild" which referes to "http://images-eu.amazon.com/images/P/3608958177.03.LZZZZZZZ.jpg" I get the following error: Access denied Could not write to /backup/SuSE-9.3/3608958177.03.LZZZZZZZ.jpg I really don't know how this became the default directory for downloading temporary files, but where can I change it again? Thanks in advance Martin
