I've been having problems with posting pictures lately. I'm getting a 102 error. I've tried switching from Lockerz to MyPict but still doesn't work. After contacting support they told me to set 'allow' on my settings and do a battery pull. I did those and it worked once but after that it went back to giving me errors. A few days after that I was able to post a picture but now it's not working again. I haven't heard from Ubersocial's support for almost a week since my last email and I sent them a follow up.
SENSfreak_03, try editing your permission settings. Might work for you.
