community builder installed , seems working fine. problem?

my users can't upload profile image, , no gallery there them select pre-loaded one. image configuration tab looks this:

path imagemagick   auto
path netpbm          auto
image software          gd2 library 
     imagemagick   not installed
     netpbm          not installed
     gd1 library      not installed
     gd2 library      auto-detected, bundled (2.0.34 compatible) 
picture                      yes
allow image upload     yes
use image gallery       yes
max. image height      500
max. image width       200
max. image filesize      100 kilobyte 
max. thumbnail height  86
max. thumbnail width   60

can me determine issue is? tried upload avatar myself, , did right things. gave me upload screen, let me browse hard drive, took little time , returned profile page default "no image selected" avatar.

worked on little today. checked tools tab in cb , said avater file in images/comprofiler not writeable.

so looked , looked , found file in fact non-existent. created it. isn't ideal solution, didn't know else try expect complete re-install.

anyway, added avatar folder default avatars listed fireboard new comprofiler file.

i able upload avatar and/or select 1 pre-existing group.

also... fyi. tried download cb1.1 again make sure hadn't missed upgrade or , compare image file structure. able download file not able unzip it. kept giving me corrupt/empty file error.
