This should be Wx::Bitmap.new('assets/images_only_btn.jpg')

It's not a method, it's a constant, and its name is 
Wx::DEFAULT_VALIDATOR. I've corrected the wrong naming of this in the 
documentation, sorry for the trouble.

By the way, this isn't going to do what I'm guessing you want - display 
a button with an image and some text. The 'name' parameter only provides 
an internal reference name to any Window; I've never seen it used.

There's no default widget to draw a bitmap + text button in wxRuby, 
because there isn't one in wxWidgets 2.8. The reason given for this is 
that that button style isn't part of the desktop standard on either 
Windows or OS X. It happens in Windows because there is little interface 
consistency, but it would look quite wrong on OS X.

If you give an ordinary Wx::Button a 'stock id' eg Wx::ID_OPEN, it will 
be given the appropriate theme image on Linux/GTK.

I think that the wx developers have given in to people frequently asking 
for this and intend to add a bitmap + text button to wx 3.0
