User pictures not displayed in MetaComment discussion

I installed MetaCommentPlugin and then PersonalInfoAddon, so that the users can upload pictures of themselves. But instead of the user pictures, the following error message was displayed in the discussion list:

Error: (2) can't find name at Main.TestUser1

I found two problems in metacomments.tmpl in the following lines:

  %IMAGE{
    "%IF{"'%web%.%topic%'/Photo"
      then="$percntFORMFIELD{\"Photo\" topic=\"%web%.%topic%\"}$percnt"
      else="%IF{"'%web%.%topic%'/attachments[name=~'\.(gif|png|jpe?g)$']"
        then="%QUERY{"'%web%.%topic%'/attachments[name=~'\.(gif|png|jpe?g)'][0].name"}%"
        else="%PUBURLPATH%/%SYSTEMWEB%/MetaCommentPlugin/nobody.gif"
      }%"
    }%"
    topic="%web%.%topic%"
    ...
  }%

1. MetaCommentPlugin uses the form field Photo, but PersonalInfoAddon uses the form field Picture. When I change the template to use Picture, the user pictures are displayed correctly.

2. The fallback expression "%QUERY{"'%web%.%topic%'/attachments[name=~'\.(gif|png|jpe?g)'][0].name"}%" does not work. In my installation, the result of the expression is the string "name". This explains the strange error message "can't find name at ...". I don't understand what is wrong with this expression.

Is there another plugin besides PersonalInfoAddon that is more compatible with MetaCommentPlugin? Do these problems occur because I use PatternSkin instead of NatSkin?
