You have to Print
rose = Import["ExampleData/rose.gif"];
Button["Show rose", Print[rose]]
plt = Plot[x, {x, 0, 1}];
Button["Show plot", Print[plt]]

=============
Dear Community,
I have a lack of understanding. (OK, I have many, but today it is about
only one of them). I want to make a button to show in my presentation
an image upon pressing. However, the operation like
Button["Image name", image_identifier] does not work. To be concrete, this:
rose = Import["ExampleData/rose.gif"];
Button["Show rose", rose]
does not return the image. I cannot get, why?
I can avoid the problem say, like this:
Button["Show rose", CreateDocument[rose, WindowSize -> {100, 100}]]
I post this question, since I would like to understand, what is wrong
with simple operators like Button["Show rose", rose] or Button["Show
rose", Show@rose] or such a variant Button["Show rose",
Import["ExampleData/rose.gif"]] and how should I choose right operators
to be used inside the Button?
Regards, Alexei
