LoadImageIntoTexture function on webplayer

Hi everyone, I am having hard times with LoadImageIntoTexture function on webplayer. While it is working just fine on editor mode(my images are loaded and i can see them on screen...), it simply cannot display them on the webplayer(i see a question mark). Here is the code of the function where it is used :

var textures : Texture2D[]; //Gallery

var textureNames : String[]; //url

function LoadImage () {

textures = new Texture2D[textureNames.Length];

 for(var t=0; t<textureNames.Length; t++)
 {
     textures[t] = new Texture2D(16, 16, TextureFormat.DXT1, false);
     Debug.Log("requesting from "+textureNames[t]);
     // Start a download of the given URL
 
     var arwww = new WWW(textureNames[t]);
 
     // wait until the download is done
     // yield arwww; // also it doesnt show my images with yield! 
 
     // assign the downloaded image to the main texture of the object
     arwww.LoadImageIntoTexture(textures[t]);
 
 }

}
