    imageButton.ImageScaling = ToolStripItemImageScaling.SizeToFit;

    // Set the background color of the image to be transparent.
    imageButton.ImageTransparentColor = Color.FromArgb(0, 255, 0);

    // Show ToolTip text, set custom ToolTip text, and turn
    // off the automatic ToolTips.
    toolStrip1.ShowItemToolTips = true;
    imageButton.ToolTipText = "Click for the current time";
    imageButton.AutoToolTip = false;
