For uploading images I am getting this message and I'm not sure what to do.

I've tried going into the design_config_files.xml to change instanes of fileUploader to imageUploader but to no avail. Anyone else have this issue?

I've experienced the issue with the uploading image to categories which I fixed by changing the mimetype function to ->_file['type'].

The issue I'm having is rather I try to insert image using either the WYSIWYG or without the editor then it won't let me upload anything.
