Unable to upload images with scribefire addon

I am having an issue being unable to upload image using the Scribefire next addon for Firefox. This is the error I am recieving

Could not write file 100_0640-150×150.jpg (Unable to create directory /home/.quim/ishiinet/keiu.org/wp-content/uploads. Is its parent directory writable by the server?

Every folder between the root and the uploads folder is set to 777 or 755. This is really annoying and I would like help getting this to work as I really enjoy using this addon otherwise. Thanks in advance.
