How does pixel restrict the appearance of the given button as images?

Using the images:

the following buttons appear unscaled in a list:

buttons = MapThread[Button["", Appearance -> {"Default" -> #, "Pressed" -> #2}] &, images]

However, by putting them in a Multicolumn, they scale poorly to match the sizes.

Multicolumn[buttons, 1]

I want them to line up in the center on the left with the same size that they appear in the List.
None Extension -> 1 in the images ni Grid with Alignment -> Left fixed up.
How to make a grid of such buttons without scaling images?

All images have the same vertical size if that matters.
