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"
         TargetFolder="~/Uploads/"
         ></telerik:RadAsyncUpload>
     <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.
