Cannot display an image from filesystem in grails

I'm new to grails (1.3.7) and I've been put in a strange situation with displaying an image from the filesystem. The one.png picture is put into web-app/images/fotos directory. The zz.gsp:

<img src="${resource(dir:'images/fotos', file:'one.png')}" alt="Nothing" />

related to the void action def zz = {} works fine. But if I intend to display the same picture in rawRenderImage.gsp:

  <body>
   <p>
     ${fdir}  <br/>   ${fname}      <!-- OK -->
   </p>
   <g:if test="${fname}">
      <img src="${resource(dir:'fdir',file: 'fname')}"   alt ="Nothing"/>
   </g:if>  
  </body>

the picture doesn't appear inspite of the parameters fdir and fname pass to the page. The action in the controller is:

    def rawRenderImage = {
//    def basePath = servletContext.getRealPath("/")
//      def basePath = grailsAttributes.getApplicationContext().getResource("/").getFile().toString() + "/images/fotos/"  
//      def basePath = grailsAttributes.getApplicationContext().getResource("/").getFile().toString()
//      def fname = params.photoId + ".png"
//      def fname = "/images/fotos/" + params.photoId + ".png"

basePath = "images/fotos"        // or basePath=”images” for /images/one.png
fname=”one.png”

        [fdir:basePath, fname:fname]
   }

Even direct assigns basePath=”images/fotos” and fname=”one.png” don't work, as well as any combinations with basePath to obtain the absolute path. Even the case when I put the picture in images directory doesn't work. I use netbeans, but it also doesn't work in console mode.

Help please.

When passing in your filename and directory as variables in the model, don't quote them in your tag's src attribute. Then the Groovy ${} evaluation will evaluate to the variables and not as Strings.

<g:if test="${fname}">
    <img src="${resource(dir:fdir,file:fname)}" alt ="Something"/>
</g:if>
