Where do I put images for icons so that they can easily be referenced in my code?

In your main activity bundle directory, you should have a subdirectory called 'icons'. In this directory, place any image files (usually in svg) format and then you can refer to those images by using the filename without the extension. For example, the activity containing the files below could refer to the following images for use with icons: 'edit-custom', 'ok-button', 'next-page' and 'prev-page'.

Annotate.activity
|-- activity
|   |-- activity-annotate.svg
|   `-- activity.info
|-- icons
|   |-- edit-custom.svg
|   |-- next-page.svg
|   |-- ok-button.svg
|   `-- prev-page.svg

Class: Icon (gtk.Image)

How do I create a button with a specific icon image?

You must first create the appropriately sized Icon object, as shown below. Then you will use the set_image() method to assign the icon to the button.

import pygtk
pygtk.require('2.0')
import gtk
from sugar.graphics.icon import Icon
...
        #previous page button
        prev_page_button = gtk.Button()
        prev_page_icon = Icon(icon_name='prev-page', icon_size=gtk.ICON_SIZE_BUTTON)
        prev_page_button.set_image(prev_page_icon)
