Remove images

Hello,
OSprop makes in each properties image-folder, sub-folders called Thumb, Original and Medium. There are the resized images. Does this mean that I can delete the orignal uploaded images? Because they are now doubled (in the properties image-folder and in the properties image sub-folder Originals)

Hi Geert,
The pictures in "Original" folder will be used to re-create the medium and thumbnail pictures through tool: Re-generate pictures
Thanks
Dam

Thank you for your reply.

So I can remove the images in the main folder 'above' Originals?
