Tested 100% in 4.2.5. Completely removes and disables the checkbox and text leaving only the URL entry.



./clientscript/ckeplugins/vbimage/dialogs/image.js

Go to Line 257

Replace

	        	type: 'checkbox',
	          id: 'remote_file',
	          label: me.editor.lang.vbulletin.retrieve_remote_file_and_ref_local,
	          labelLayout: 'horizontal',
	          setup: function() {
		        	if (me.editor.config.vbulletin.attachinfo)
					{
		        		this.setValue(true);
					}

With this

	        	type: 'checkbox',
	          id: 'remote_file',
	          //label: me.editor.lang.vbulletin.retrieve_remote_file_and_ref_local,
	          label: '',
	          labelLayout: 'horizontal',
	          setup: function() {
		        	if (me.editor.config.vbulletin.attachinfo)
					{
				        this.getElement().hide();
		        		this.setValue(false);
					}

and then in additional.css add this

.cke_dialog_ui_checkbox_input {
display:none;
}
