Image Uploader - Upload multiple folders

I know that something similar is possible with “one-pane” layout: we can add the images from different folders to the “upload” area and click “Send” to upload them, but in this case all the images go to 1 folder and we lose the folder structure.

In other words, what we would like to do is:

- If we have 3 folders of images named: Folder1, Folder2, Fodler3

- We go to image uploader, and select the 3 folders and click “Upload”

- The 3 folders of images get uploaded on our server with their folder name as follows: Folder1, Folder2, Folder3 and each folder will contain their corresponfing group of images.

Is this possible? If not, how much will it cost to implement it? How long will it take to develop it?

Thanks for your great support.
