Assuming pyqt supports gif pictures, this should work
假设pyqt支持gif图片，这应该有效
icon = QtGui.QPixmap('add.gif')
button = QtGui.QPushButton()
button.setIcon(icon)
Push buttons display a textual label, and optionally a small icon. These can be set using the constructors and changed later using setText() and setIcon(). If the button is disabled, the appearance of the text and icon will be manipulated with respect to the GUI style to make the button look "disabled".
按钮显示文本标签，以及可选的小图标。这些可以使用构造函数设置，稍后使用 setText() 和 setIcon() 更改。如果按钮被禁用，文本和图标的外观将根据 GUI 样式进行操作，使按钮看起来“禁用”。

Example:
例子：
from PyQt4 import QtGui, QtCore
class Window(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.button = QtGui.QPushButton('', self)
self.button.clicked.connect(self.handleButton)
self.button.setIcon(QtGui.QIcon('myImage.jpg'))
self.button.setIconSize(QtCore.QSize(24,24))
layout = QtGui.QVBoxLayout(self)
layout.addWidget(self.button)
def handleButton(self):
pass
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec_())
