Например так:

lib.img_with_popup = COA
lib.img_with_popup {
  10 = IMG_RESOURCE
  10 {
     file {
       import = uploads/pics/
       import.current = 1
     }
     stdWrap.wrap = <a href="javascript:image_viewer(|)">
  }

  20 = IMAGE
  20{
    file{
      import = uploads/pics/
      import.current = 1
      width.field = imagewidth
      height.field = imageheight
      maxW = {$styles.content.imgtext.maxW}
      maxW.override.data = register:maxImageWidth  
    }                      
  }
  
  wrap = |</a><br>
}
