Image Carousel and Content Type

Question

I have some URLs for images and PDFs that are being put the SAP Carousel. I'm having the following issue. The URLs I'm using are links to documents in FileNet....which don't end with the file extension...they end with a GUID of the document like so:
http://www.someplace.com/WorkplaceXT/getContent?mode=download&objectStoreName=test&objectType=document&id={97F6083D-D679-41AB-8758-BD2AEEF14E69}
The only place I've seen where I can tell if the file is an image or a PDF is in the Response Headers for that image URL in the "Content-Disposition" header.
Let's say I have 3 images/PDFs...
<img src="http://www.someplace.com/WorkplaceXT/getContent?mode=download&objectStoreName=test&objectType=document&id={97F6083D-D679-41AB-8758-BD2AEEF14E11}"/>
<img src="http://www.someplace.com/WorkplaceXT/getContent?mode=download&objectStoreName=test&objectType=document&id={97F6083D-D679-41AB-8758-BD2AEEF14E69}"/>
<img src="http://www.someplace.com/WorkplaceXT/getContent?mode=download&objectStoreName=test&objectType=document&id={97F6083D-D679-41AB-8758-BD2AEEF14E55}"/>
What is the best way for me to tell what type of content is actually represented? Can I access the "Content-Disposition" header easily when I load each of the images/PDFs from the URL?

hi
try something like this.
declare
      f varchar2(100);
begin
     f := webutil_file.file_open_dialog();
     if f is not null then
          :block.item := f;
          end if;
     end;or try the following code.
declare
l_file_name varchar2(383);
begin
l_file_name := webutil_file.file_open_dialog( );
if
  l_file_name is not null
then
  if
    :block.rowid is not null
  then
    create_record;
  end if;
  client_image.read_image_file ( l_file_name, substr ( l_file_name, instr ( l_file_name , -1 ) ), 'block.item' );
end if;
end;sarah
