LG VX-8500 Chocolate

I went to my pictures and was viewing on then i went to options then pix place just to see what it was about and when it started saying sending message i pressed the end button to cancel it and then it said can not cancel message then when i went to the main screen my background turned to a big pitcher of white milk and i dont have it in my pictures or anything so i was wondering if that ever happened to anyone else or why it happened to me?? thank you 😁
