[Solved]: Pictures show up in Album/userpics/ but not in program

[mrall]

First of all let me say this is a really great application.

After uploading a picture and placing the labels in the album and category this is the error that display on the top of the screen.

The previous file could not be placed.

You have successfully placed all the files.



I have the debug on as well and it displays the following:

/upload.php

   * Notice line 2191: Undefined index: user1
   * Notice line 2192: Undefined index: user2
   * Notice line 2193: Undefined index: user3
   * Notice line 2194: Undefined index: user4

/include/picmgmt.inc.php

   * Notice line 205: Undefined index: OS
   * Warning line 219: shell_exec() has been disabled for security reasons
   * Warning line 225: unlink(albums/userpics/thumb_cindy~5.jpg) [function.unlink]: No such file or directory

Is this all because the shell_exe() is disabled?
I don't have the access to enable this command.
Is there a way around this?

Thanks for any help
