GraphicsGrid with empty elements

Question

Here is a nice figure

Now let's create a grid

plot = Show[GraphicsGrid[{{im1, im1, im1}, 
            {SpanFromLeft, im1, im1}, 
            {SpanFromLeft, SpanFromLeft, im1}}, Spacings -> 0]]

which produces

As you can see, three dots (...) appear at the empty slots of the grids.

My question: Is there a way to remove these dots?

Many thanks in advance!

In:

im1 = Import["https://i.stack.imgur.com/e6Kuf.jpg"];
UpperTriangularize@Array[1 &, {3, 3}] /. {1 -> im1, 0 -> ""} // GraphicsGrid

Out:

Thanks to Kuba && J. M.. I didn't know I could use "" instead of a white rectangle. And J. M.'s method is more compact.

$\begingroup$ blank = "" will be enough. $\endgroup$

$\begingroup$ As Kuba says, "" suffices. Here's a compact version: GraphicsGrid[PadLeft[{{im1, im1, im1}, {im1, im1}, {im1}}, Automatic, ""]] $\endgroup$

You can just use Null instead of SpanFromLeft:

im1=Graphics[Disk[]];

plot = Show[GraphicsGrid[{{im1, im1, im1}, 
        {Null, im1, im1}, 
        {Null, Null, im1}}, Spacings -> 0]]

This will produce no dots.
