Weird characters displayed on page instead of file download/preview

Question

Hi everyone,
I have a download file procedure as per the instructions on the download.oracle.com page
The download of the files worked just fine (or better say they were previewed in a new page) but recently a new schema has been added to the workspace so we can start the testings from the scratch.
I modified the schema name where needed, but not the download page acts kinda weird, as instead of the file preview, I get a long page full of:
�����JFIF�,,����&�Exif��MM�*������������������b�������j(�������1�������r2���������i�������������-����'�-����'Adobe Photoshop CS3 Windows�2008:07:28 16:41:20���������������������������]��������������������������&(�������������.������%��������H������H��������JFIF���H�H�����Adobe_CM�
The issue is that if I switch back to the old schema, the result is the same. So, anyone has any idea of what can cause this?
Thank you
Regards
Andrea

Thanks!
PS: Some updates...I tried it in IE as well (I use FF when working with applications) and funny enough the photos and documents get displayed/the download box shows up.
But, all the files have the name f. f.pdf, f.jpeg etc
I tried calling the dl_image procedure in the url (currently I call a new page where I pass the file id to an application id and then I call the above procedure in a pl/sql block):
http://www.host/pls/dad/schema.dl_file?p_fileid=1
And the name seems ok. I don't think it's a good idea to put the procedure name in the link, is it?
