var frameHeight = 33;
var frameMarginLeft : int = 10;
var frameMarginTop: int = 10;
function Start () {

}

function Update () {

}
function OnGUI()
{
	 GUI.DrawTexture( Rect(frameMarginLeft,frameMarginTop, frameMarginLeft + frameWidth,frameMarginTop + frameHeight), frameTexture, ScaleMode.ScaleToFit, true, 0 );
}

Mark you texture as type GUI or set the Wrap Mode to Clamp. Those border pixels you’re seeing are actually appearing because the GPU is automatically reading pixels from the other side of the texture.
