This is a sandbox project, which contains experimental code for developer use only.
Simple module to extend the editor (CKeditor) image dialog so that images can be used/placed inside the editor with a image style applied.
IMPORTANT: Currently the module (output of the module) only works if the "Restrict images to this site" filter inside the textformat is deactivated.
