I have found an other function : gtk_image_new_from_file. And with this 
function, it's good. I don't know why but it's good.

pixmap = gtk_image_new_from_file("../Back-prelight.png");
gtk_toolbar_insert_item (GTK_TOOLBAR (toolbar),
             "Back",
             "bla bla",
             NULL,
             pixmap,
             NULL,
             NULL,
             -1);
