How to disable image preview in the editor

[principino1984]

Hi, I've got a problem, I'd like to disable all the images preview (from smiles to all the other images) in the editor. I mean when I click on i dont want to see the preview in the editor, but just the link with the tags i.e. [img]xxx.jpg[/img] as it is in this forum!! Same for the smiles, when here you click on the smiles it shows the code and not the preview.

How can i do it?

thanks a lot

Marco
