Adam,
I did that:
<ce:editor id="Editor2" DisableAutoFormatting="true" RemoveServerNamesFromUrl="true" UseRelativeLinks="true" runat="server" activetab="View" filespath="./CuteEditor"></ce:editor>
And now I've got:
<img height="600" src="http://dknb/PromolPM/uploads/ObjektLang_9108_1_Spezifik/Wasserlilien.jpg" width="800" border="0" />
But when I copy the app to another server it should be eg.:
src="http://clserv/test/uploads/ObjektLang_9108_1_Spezifik/Wasserlilien.jpg"
