Didn't it occur to you that it is important to include exactly how you used the function in the report? What is the report query?
but i face these problems
1- the images don't appear when i run the report and all images are blank
2- i must press edit on any column and go to edit page then back to report again and the image appear
3- all record have the same image ( the image with id which i pressed )

Sounds like you're passing item values from the edit page to the function rather than column values from the report. See the SELECT example in the <tt>apex_file.get_blob_file_src</tt> to see how to use the function in a report. The values of <tt>p_v1</tt> (and <tt>p_v2</tt> if required) should come from report columns, not page items.

Why do you need to use the function at all? Using declarative BLOB formatting is recommended.

Can you explain how you got the image to show?  I have a similar issue with trying to GET a blob image using RESTful web service.  I am putting the BLOB field into a collection item 'BLOB001' , but I cannot figure out how to get the Image to actually render in a report with that BLOB item:

select blob001 "image_blob"

from apex_collections

where collection_name = 'P5_DOREST_RESULTS'

The declarative Blob Column Attributes section does not accept the collection above as a table so it won't set the attributes.  Is the only alternative to load the BLOB into a table and then create a report on that?

Thanks,
