oke update.. i installed NewsPress theme on a testsite on my compagnies website. http://hbpmedia.nl/wf7/ and quess what.. the same problems with the images and not saving the newspress options.
so it looks more a WP problem and not a D5 problem. The only crap thing now is that WP and the helpdesk better be named helldeks. you have to wait for months before you get a anwser đ
