Ok. I'm running AME 2.5.6, which differs from your 2.5.

I'm running that one too. It just says 2.5 here on vb.org but the downloaded version is 2.5.6 so we have the same one.

The only difference between us is that I had no validation code and my regular expression was slightly different from yours, like this:

http://[\w.\]+youtube\.[\w]+/watch[\?\#!]+v=([\w-]+)[\w&;+=-]*[\#t=]*([\d]*)[&;10shdq=]*

The replacement code was the same. I now took over all your code, have "extract destination data" set to "yes" and saved a post, but the same problem still occurs.
I already tried several solutions given from page 92-100, nothing works.

Strange thing is that also with some older posts, the images are visible, but are present 2 times with some code in between. The solution given to that problem however, does not work either.
So thank you for trying to help, but it seems not as easy as to read some posts here to find the solution I guess. Tried that already.

Then about Downloads II. You could use that to provide certain upload rights. The problem however would be linking to those files then, because your users would not know the filename on the server.
For example, if you upload a file called mymusic.mp3 with DownloadsII, the file will be called something like 4472-mymusic.mp3 because Downloads II will generate a number for every upload made and they all com into 1 directory.
So I guess you can probably better try a script like BirdoPrey5 suggested.

Now I hope Cyb will come by and fix my Ame problem.
