import os, base64

icon = open('ya.png','rb')
iconData = icon.read()
iconData = base64.b64encode(iconData)
LIMIT = 60
liIcon = []
while True:
        sLimit = iconData[:LIMIT]
        iconData = iconData[LIMIT:]
        liIcon.append('\'%s\'' %sLimit)
        if len(sLimit) < LIMIT:
                break
print os.linesep.join(liIcon)
