Somewhere you create the pushbutton uicontrol. Something like

uicontrol('...

Make sure to do that with a variable on the left-hand side:

H2pushbutton = uicontrol('...

That way you get a handle variable to that uicontrol that you can use to get and set its properties. Try:

get(H2pushbutton)

...to get a listing of the properties you can set.

"yourimage" is simply my whimsical variable-name of the image you want to set the uicontrol icon to. You have to load it somehow, don't you?

HTH,

H2thisthatorthenext is just a simple mnemonic for "handle to this that or the next". For future ease of code maintenance make good use of descriptive variable names, in my experience it doesn't really matter if you mix different styles a bit (_ as a word separator, camel-case etc) but it really helps to have names that are descriptive in some explicit way.

You can set the 'CData' property of the uicontrol:

rgb = rand(10, 20, 3);
a = uicontrol('cdata', rgb);

GUIDE is a program to design GUIs, therefore you cannot insert a picture into it. The original question sounds, like you want to display a picture inside a pushbutton. If you want to get anything else, please explain this more detailed. What does "define a picture to pushbutton" exactly mean?
