Change an image on a button

[Guillaume Charhon <pub charhon wanadoo fr>]

Hi,
I've some problems to change an image on a button.
See the example :

gtk_button_set_image(GTK_BUTTON(theButton), ImageOne); // ok
gtk_button_set_image(GTK_BUTTON(theButton), ImageTwo); // ok
gtk_button_set_image(GTK_BUTTON(theButton), ImageOne);  // ImageOne 
doesn't appear !


Thanks !
