Stop Multiple Image size creation when importing folders into Wordpress Media Folder

Hi,

How do you stop your plugin from automatically creating different size versions of images within a folder that is been imported into the Wordpress Media Folder using your Import server folders tool ?

I have FTP'd a large amount of images withing categorised folders, but when I use the Import Server folders, it starts importing the folder and images , but also creates multiple different sizes of each image file???

I have disabled Media Thumbnail creatin in wordpress, also through the functions file and even tried installing Thumbpress, BUT no joy ?

When I upload an image through the wordpress media tool, it does not create any additional different sized images, it ONLY happens when I import using your tool ?
