Filebrowser - Only show images

Hi,

Does anyone know if it's possable to list only images in the filebrowsers when accessed through the image icon?

At the moment it lists all files within a given directory, but I only want it to list images. I know the default is seperate folders for each type of file, but I'm trying to integrate FCKeditor into an exsisting site which has every filetype in the same folder.

I'm using the ColdFusion version...

Thanks, Paul.
