For interest sake, re copyrights

[convictor]

On my site I used various scripts from here, eg mp3 search etc. What I want to know, if I edited the scripts, and add a credits page, where it says where the scripts come from, and the coders of those scripts, would that be a problem with the various coders? I don't want someone stumble onto my site and feel I stole their scripts, so that's why I want to add the credits page.

Go one.. No scripts are proven be made by them.. There is no copyrights found at the bottom of their scripts either.. If there is copyright, be up to good only..
