    Hi Emiliano,

    It is not a good idea to display images from the Temporary folder, because it is cleared periodically. Better display it from the Target folder.
    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" MaxFileInputsCount="1" OnFileUploaded="RadAsyncUpload1_FileUploaded"
         <telerik:RadButton ID="rbUpload" runat="server" Text="Upload"></telerik:RadButton>
         <telerik:RadBinaryImage ID="RadBinaryImage1" runat="server" />

    protected void RadAsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
        string ext = e.File.GetExtension();
        if (ext == ".png" || ext == ".png")
            RadBinaryImage1.ImageUrl = "Uploads/" + e.File.FileName;

    This Code Library shows how to preview selected images on the client.
