nautilus-image-converter can't resize images to a folder

When resizing multiple images with nautilus, it would be intuitive if you could append a /folder-name to a filename to make the files to be resized to a subfolder. Even better there might be a third option to for a folder as below:

1) Append
2) Resize in place
3) Resize to a folder

Folder name would be defaultly 'resized' and it would be created if didn't exists. It would be also nice to have a browse button to select an existing folder.

I'm not sure if this is already possible with nautilus, but at least it's not very intuitive. The nautilus-image-converter is still very good tool and for notices easy to aproach. In my opinion it should be defaultly installed as this is easy and very basic photo modifying tool.
