When an image or document is uploaded into an editor is there a way to modify the targeturl before the html code is inserted?

 

Here is the scenerio. 

 

I have a file path of: account/username/images  which maps to the appropraite file on the server.  I want to change this path just before the link or image is inserted in the editor to images/filename. 

 

Can you think of a somehwat easy way to accomadate for this.  IN ver 3.  I could hard code the

parent.imgname.value='" & "/images/" & folpath & fil.name & "';
in the browse_imag.asp file and the browse_document.asp file.
