You could also create a new Admin account and you should be able to login and take the img out of the trash.
===========================================
How to create a permanent or temporary admin account onto an Apple computer from single user mode.
Boot the computer holding ‘Command + S’ to enter single user mode.
You need to run these two commands to finish the initial boot process:
/sbin/fsck –fy
This command will force a disk check. Necessary just to be sure there are no errors. Wait a few minutes while it completes. (This step is optional so if you are in a hurry you can skip it) If an error is found run it again until they are all fixed.
/sbin/mount –uw /
This command mounts your hard drive, and must be performed.
Once in single user mode the first thing we need to do is start the system daemons. Run this command:
sh /etc/rc
This is the normal startup script, it’ll do the necessary work of getting the system (mostly) up and running, but not exit single-user mode or start the GUI. After the startup script has executed press enter to get a new prompt.
Now that we have the system loaded, we can create an administrator account using niload. To do this you need to run a command to populate the NetInfo database with the appropriate information for a user account. To do this we use the niload command to load the information directly into Netinfo. It uses the format of a standard passwd file, which is a series of fields separated by colons.
Here is the standard passwd format and what the information in the ten separate field’s means:
john::530:530::0:0:John Doe:/Users/john:/bin/bash
These fields correspond to the following template:
1:2:3:4:5:6:7:8:9:10
Field 1: The user’s short name in this case, john.
Field 2: The user’s password; we’ll set this later with another command.
Field 3: The user ID number.
Field 4: The group ID number. For Panther, this is the same as the user ID number.
Field 5: A comment field; you don’t need to enter anything here.
Field 6: The user’s class; not used by NetInfo.
Field 7: The user’s password change time; not used by NetInfo.
Field 8: The user’s full name.
Field 9: The user’s home directory path.
Field 10: The user’s default shell.
If the following command you need to use a uid that is not in use. Run this command to find out which user IDs are used: nireport . /users name uid, and choose an ID above 500.
Now let’s create that user. (this command must be all on one line):
echo ‘john::530:530::0:0:John Doe:/Users/john:/bin/bash’
| niload -v passwd /
‘1 items read from input
Netinfo /users contains 22 items
Processing input item:
_writers_passwd: john
change: 0
class:
expire: 0
gid: 530
home: /Users/john
name: test3
passwd:
realname: John Doe
shell: /bin/bash
uid: 530
writing new directory /users/john’
After you have created the new user, you need to set the users password. Run this command and enter the password twice when prompted:
passwd john
Changing password for john.
New password:
Retype new password:
Finally, you need to create a group for the user; Tiger uses individual groups for each user, which have the same GID as the user’s UID:
echo ‘john:*:530:john’ | niload -v group /
This command creates the group named john, gives it the GID of 530, and adds the user john to the group, all in one step.
Finally, let’s make this user a member of the admin group so they have administrative access. Run this command to add the user to the admin group:
niutil -appendprop / /groups/admin users john
Your new user is an administrator and has all administrative rights.
