if you have the PSPersonalize + % folder they go in the psp\game folder
then you need your 12 pictures, which need to be:- 300x170 res 24bit pictures and less than 150kb. once you have your pictures place the in the root of your memstick (same place as "psp" folder) named as:-
01.bmp (January)
02.bmp (February)
dito
dito
12.bmp (December)
note do not include "(January), (February) etc"
Once you have all twelve go in to the xmb and lauch the pspersonalise homebrew

p.s. id recommend if your a newbie just download the latest devhook and utilize the wallpaper changing in emulated 2.71fw its easier and safer
