I've been meaning to do this for a while.  Recently, I've noticed some uploads that have had comments by other members saying the file was scanned by them, usually some time ago. Yet it looks like the uploader also scanned it as there is no note to the contrary.
It would be a good idea if when uploading a file you haven't scanned yourself to at least mark it unknown.
If you know where you found the scan, a note to that effect would help.
So, an upload could look like this:-
"Uploaded   September 8, 2016  by pawbroon/scanner unknown"

in this example, I uploaded a file but I don't know who scanned it.

If you know where the scan originated leave a note on the index card.

I've been doing it round the wrong way so from now on I'll follow this layout.
Always good and polite to give credit where it's due, or at least note that you didn't do all the work yourself, which is a particularly important point to remember for folk like me who excavate files from all sorts of obscure corners of the internet.

paw broon, do you know of any free service to help remove IFrame from a website ?

Sorry, old bean, I don't. I've read up on IFrame but I'm pretty useless with the complicated computery stuff.

Looks like you will have to get the help of a friend who knows how to work in command line with Java.   
Here's a site with comprehensive info on IFrame.
