Custom Node Image is Distorted/Compressed left to right axis

SD.PNG is the original image .

Any ideas about the Distortion and Compression on the left to right axis ?

I discovered the target area is square, so the image is compressed to fit in the square target area.

It would be useful to be able to have many custom icons to represent distinct nodes.

I see that if you create a custom node, then add a new custom node, it overwrites the first custom node.

If you could create many custom nodes, it would make understanding the relationships between nodes easier.
