Apple weblog


Hi, I have tried to enable a weblog for intranet collaboration, and finally I could set up apple weblog for that but then when I wanted to go further I searched internet to find out how to upload images and show them in the web log, but when I tried this with word or excel or pdf files, the program for uploading (ecto) sends an error regarding MIME types error, though only photos or sound files can be uploaded. Any hint?
