Hello alex

Are you talking about this lock screen walpaper ?

If yes then set the Live Xperia wallpaper and you will have this lock screen wallpaper automatically.

To do that, tap and hold anywhere on the homescreen > wallapapers > live wallpapers > Xperia > settings > chose any colour > set as wallpaper 

You will have the above lock screen wallpaper set already.

I'm uploading it here as well. ( it's 5.6 MB high resolution photo)

If this is not the photo you want, then show me the one you want and I'd try to help you with it.

Regarding the abnormal crashes, you could do a software repair on your phone that would reinstall the Operating system and remove glitches, increase performance and enhance your experience.

Download Xperia Companion http://support.sonymobile.com/global-en/tools/xperia-companion/ on your PC and install it. Select "software repair and follow the on screen instructions.
