For Photosphere (I tested & it works. Thanks for ktz985)
You need to install/flash the "camera42_patched_v2.zip"- Package via your recovery.
Just google for "camera42_patched_v2.zip" (I'm not allowed to post a link )
For me it works perfect on my NexusS cm10.1 (20120103) but you have to disable the "GPS position" otherwise the gallery-app will crash during the rendering.
Not to forget: after installing/flashing you will have two gallery apps. The new one has all you need including picasa sync. You can uninstall the old one by using a root file explorer and deleting "/system/app/gallery2.apk".
From Cyanogen mod Google+ page
# CM 10.1 is based on Android 4.2.1. Any and all proprietary applications that you have installed outside of CM should be updated to their 4.2.1 counterparts. Do not use the 4.1 versions of proprietary applications, else you will experience difficulties. # Do not use the CyanogenMod Updater to go from 10.0 to 10.1. While you will have a functional rom, due to the 1st bullet point, you will be left without your proprietary applications and their data. We highly suggest performing the initial install manually via recovery (flashing CM and your addons). Once you are on 10.1, you can use the CM Updater as per normal. # You do not need to wipe when updating to 10.1 if coming from an earlier CM version. However, as we mentioned in the weekend's PSA, users updating (instead of wiping) will experience a conflict in the application data for the Clock app. You are advised to clear this apps data on first boot of 10.1. # Another item to note is that the support for the 10.0 feature that allowed for an expanded number of targets on the pattern lockscreen is not in 10.1. If you use this lockscreen, disable it before updating from 10.0. # Finally, we always advise that you create a backup before any update. Do note, however, that due to Android 4.2 changes to support multi-user mode, your backups will automatically be transferred to /sdcard/0/[backup folder]. Remember this when attempting to restore 10.0.
