Make sure to protect the Install Tool with another password than "joh316".
Better yet you can add a die() function call to typo3/install/index.php after usage.

IF THE INSTALL TOOL CRASHES...
The Install Tool is checking PHPs support for image formats. However certain versions of PHP (fx. 4.3.0 with bundled GD) will crash when trying to read the PNG test file. If this happens you will see a blank screen or error message.
Workaround: Open the file typo3/sysext/install/mod/class.tx_install.php, go to the line where the function "isPNG()" is defined and make it return "0" hardcoded. PNG is not checked anymore and the rest of the Install Tool will work as expected. The same has been known with the other image formats as well. You can use a similar method to bypass the testing if that is also a problem.
On behalf of PHP we regret this inconvenience.

BTW: This Install Tool will only work if cookies are accepted by your web browser. If this dialog pops up over and over again you didn\'t enable cookies.

                                        Installing TYPO3 has always been a hot topic on the mailing list and forums. Therefore we've developed this tool which will help you through configuration and testing.
                                        There are three primary steps for you to take:

                                        <strong>1: Basic Configuration</strong>
                                        In this step your PHP-configuration is checked. If there are any settings that will prevent TYPO3 from running correctly you'll get warnings and errors with a description of the problem.
                                        You'll have to enter a database username, password and hostname. Then you can choose to create a new database or select an existing one.
                                        Finally the image processing settings are entered and verified and you can choose to let the script update the configuration file, typo3conf/localconf.php with the suggested settings.

                                        <strong>2: Database Analyser</strong>
                                        In this step you can either install a new database or update the database from any previous TYPO3 version.
                                        You can also get an overview of extra/missing fields/tables in the database compared to a raw sql-file.
                                        The database is also verified agains your 'tables.php' configuration (\$TCA) and you can even see suggestions to entries in \$TCA or new fields in the database.

                                        <strong>3: Update Wizard</strong>
                                        Here you will find update methods taking care of changes to the TYPO3 core which are not backwards compatible.
                                        It is recommended to run this wizard after every update to make sure everything will still work flawlessly.

                                        <strong>4: Image Processing</strong>
                                        This step is a visual guide to verify your configuration of the image processing software.
                                        You'll be presented to a list of images that should all match in pairs. If some irregularity appears, you'll get a warning. Thus you're able to track an error before you'll discover it on your website.

                                        <strong>5: All Configuration</strong>
                                        This gives you access to any of the configuration options in the TYPO3_CONF_VARS array. Every option is also presented with a comment explaining what it does.

                                        <strong>6: typo3temp/</strong>
                                        Here you can manage the files in typo3temp/ folder in a simple manner. typo3temp/ contains temporary files, which may still be used by the website, but some may not. By searching for files with old access-dates, you can possibly manage to delete unused files rather than files still used. However if you delete a temporary file still in use, it's just regenerated as long as you make sure to clear the cache tables afterwards.

                                        You would think that this script should rather be a module in the backend and access-controlled to only admin-users from the database. But that's not how it works.
                                        The reason is, that this script must not be depending on the success of the configuration of TYPO3 and whether or not there is a working database behind. Therefore the script is invoked from the backend init.php file, which allows access if the constant 'TYPO3_enterInstallScript' has been defined and is not false. That is and should be the case <i>only</i> when calling the script 'typo3/install/index.php' - this script!
