[Q] Installing Clockworkmod only

Hi all,

been a while since upgrading and always seemed to get help, so now im stuck i thought id bob back and ask again.

my friends father passed away recently, leaving his mobile locked with all family photos stored on the device, the device has no sim card as this has been cancelled and no memory card, the photos are on the actual phone.

the phone works but when powered on it prompts for the pin code. i dont want to try too many attempts and lock the phone. ive tried download mode, then connecting to PC, i can see the memory card but says please insert when i click it.

on my older phone i had CWM recovery installed and could mount the the storage card, will this work for the internal storage too ??
i dont need the phone, i just cant risk loosing precious photos...is installing CWM an option or is there another way of accessing the memory card while still locked.

the only information i have is that is a Galaxy s I9000, i have no idea which version of andriod is running

thanks for reading and hopefully someone can help

cheers craig
