Sending CK A List Of Images

Can you tell CKFinder what images can be inserted via, say, PHP? Send it a list of images rather than browse a folder? The reason I ask is that I have about 7000 images all stored in a central folder, but out of that 7000, only about 10 will be applicable to any particular article?

It would be handy to be able to send CKFinder a list of images in PHP array format that it can use, eg

$images = array (
"image1.jpg",
"image2.jpg",
"image1231.jpg"
);
