Check to see how old Gallery version 1.5.6 is.

This version of Gallery was released on 04/03/2007. You can check for more recent versions by visiting http://gallery.sourceforge.net.

Check to see if you are running a supported Version of PHP.
Due to bugs and missing functionality in some PHP versions, the minimum PHP version for Gallery 1.5 and newer is at least PHP 4.1.0

PHP v5.2.12 is OK.

Gallery highly recommends that the PHP option 'register_globals' be turned off, for security purposes. Some software, notably the 'Geeklog' CMS, requires that 'register_globals' be enabled.

register_globals is off.

Check to see if PHP is running in safe_mode. Safe Mode is a PHP security feature commonly used in shared environments. Gallery cannot run when Safe Mode is enabled because it imposes too many restrictions.

safe_mode is off.

The exec() function is what Gallery uses to launch programs such as NetPBM, ImageMagick, and jhead. If exec() is disabled on your server then Gallery will not be able operate.

exec() is enabled on this server.

Allow the Gallery .htaccess file to set application specific configuration options for the Gallery application. This is controlled by the webserver owner so it's not always possible for you to change it. The main drawbacks to not having this are that you may not be able to upload files > 2MB (e.g. big ZIP files or movies).

I can read your .htaccess file.

Check to see if magic quotes are enabled on your PHP server. If they're on, you may notice strange behavior if you put ' (single-quote), " (double quote) or \ (backslash) characters in titles or captions in Gallery.

magic_quotes are off.

Check to see if your webserver is compiled with mod_rewrite. This Apache module allows Gallery to use shorter URLs that are easier to read and look nicer when you mail them to your web-challenged relatives. It's not an essential feature.

mod_rewrite is enabled.

Check to see if NetPBM is installed so that Gallery can manipulate images (rotate, resize, make thumbnails, etc.). You only need to have either NetPBM or ImageMagick installed.

I can't find NetPBM. If it's installed and not in the path of the webserver user that's OK—you can specify the path to NetPBM by hand on the following page. If it's not installed, you have two choices:
Gallery prefers NetPBM version 9.9 and up. You can install just the binaries Gallery needs from the Gallery Download Page. Or, you can compile and install the entire NetPBM package from the NetPBM website.
Note: You can install the binaries from the Gallery site even if you don't have root access on your box! If you can't get it working, try leaving the NetPBM path blank and using ImageMagick instead.

Note:Your PHP installation is configured with the open_basedir restriction. This may make it difficult for Gallery to detect and verify your binaries, even if you've already successfully used the Config. Wizard in the past. Don't worry too much if this page gives warnings; your settings will still be saved properly.

Check to see if ImageMagick is installed so that Gallery can manipulate images (rotate, resize, make thumbnails, etc.). You only need to have either ImageMagick or NetPBM installed.

I can't find ImageMagick. If it's installed and not in the path of the webserver user that's OK—you can specify the path to ImageMagick by hand on the following page. If it's not installed, you must install it.
Gallery prefers ImageMagick version 5.4.8 and up. You can compile and install the entire ImageMagick package from the ImageMagick website.
Note: The site also has binaries available for assorted operating systems. If you can't get it working, try leaving the ImageMagick path blank and using NetPBM instead.

Note:Your PHP installation is configured with the open_basedir restriction. This may make it difficult for Gallery to detect and verify your binaries, even if you've already successfully used the Config. Wizard in the past. Don't worry too much if this page gives warnings; your settings will still be saved properly.

Check to see if jhead is installed so that Gallery can examine EXIF headers embedded in images created with most digital cameras.

I can't find jhead. If it's installed and not in the path of the webserver user that's OK—you can specify the path by hand on the following page. If it's not installed, you can install it yourself. Jhead is a public domain EXIF parser. Source, linux binaries, and windows binaries can be found at the jhead homepage.

Check to see if jpegtran is installed so that Gallery can perform lossless rotations on JPEG images.

I can't find jpegtran. If it's installed and not in the path of the webserver user that's OK—you can specify the path by hand on the following page. If it's not installed, you can install it yourself. Jpegtran is a free tool distributed by the Independent JPEG Group as part of libjpeg. Source may be found at the IJG homepage. Binaries may be found at the JPEG Club website or in the libjpeg package of Linux distributions.

Check to see if PHP is compiled with GNU gettext support for fast translations.

PHP has GNU gettext support.

Check to see what languages are available.

It seems you didn't download any additional languages. This is not a problem! Gallery will appear just in English. Note: If this is not true, check that all files in locale folder are readable for the webserver, or contact the Gallery Team.

Checking to see if you have the latest versions of all Gallery files.

All tested files up-to-date.
