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
