How can I get my own picture as my home screen wallpaper using Cydia?

My iPod is too old to set a background behind all my apps, so I'm using Cydia but User Wallpaper 4 doesn't work for some reason. Any other tweaks you know of? Please don't say Simple Background, that doesn't work either. It doesn't let you choose your own picture. Thanks so mucch(: By the way, I have 4.2.1
