I tried to put jpg image like background ti my application. First time I tried with FreeImage library, but the image didn’t show. Second time i tried with Gdiplus, i opened the image but when i opened and the object the background disappeared. I will send link to my project, If someone have any ideas i will be so happy, because I haven’t yet. Thanks!
