it's probably because your image folder hasn't got full modify/write permissions

I got the following error when I am adding a new categories. We have already given full write permission to Images and images\thumbs folders

Did you find a solution for your problem as i am having the same problem when creating or chaning the images for a category.

still looks like a permission problem - grant ( or ask your hosting provider to grant) write permissions to images/thumbs directory
