Connect your PSP to your computer via its USB cable.
Unzip the newest ChickHen software on your computer.
Copy the unzipped h.bin file to the memory stick root, which stores all the picture, PSP and video folders.
Copy the entire ChickHen folder to the the PSP's "Photo" folder located at "X:/PSP/PHOTO." Manually create the "Photo" folder if it does not already exist.
Disconnect your PSP from the USB cable. Turn off your PSP completely. Make certain it is powered off and not just in "standby" mode. Restart the PSP.
