Dreamweaver, Smarty & Popup

Hi everybody, another question about the use of dreamweaver with smarty. I use the popup function in tags such as <IMG>, and Dreamweaver highlights the syntax in the wysiwyg editor. It's quite awful, but the most important thing is that as the syntax of the popup function is very long and so my tables are unreadable !! I use this kind of delimiters: <:--{ and }-->. A workaround please? Thanks,
