                          || 'src="' 
                          || apex_util.get_blob_file_src ('P61_EMP_IMAGE',
                                                          c.party_id
                                                         )  // Generates a call to the apex_util.get_blob_file that can be used to  download a BLOB column content

  1. Hi Doyen, I am trying to display images in an IR, but I got a square with a cross instead of the image, your post is helpful but I have trouble to understand exactly what to set in Step 3, I don't find Column Name in Report attributes, is it a Region property? or a Column property? or the Report attributes properties?
    I am running Apex 5 and I don't find the property to set.
    I know the get_blob_file_src is getting the data properly because I display the column as text and has all the a, p, I, p_pk data

    Thanks in advance
    Leticia
