Typically, default server configuration does not allow uploading files with Image Uploader. This topic describes how to configure a server you are going to deploy Image Uploader on properly.

## Configuring Permissions

The folder where you are going to save files should have modify permissions. Depending on your operating system it can be set in one of the following ways:

- On Windows NT/2000/XP you should grant the modify permission to the Internet guest user (IUSR_<machinename>).
- On Windows 2003 Server you should grant the modify permission to the NETWORK SERVICE group.
- On Windows Vista/2008 Server/7 you should grant the modify permission to the account your site application pool is running under, Network Service by default.
- For *NIX systems you should specify read and write permissions.

## Configuring Maximum POST Request Length

Usually, a limitation for maximum POST request length is specified to reduce the risk of DoS attacks. If the request size exceeds a specific value, it is considered malicious and the upload would be broken.

### Editing PHP Configuration Files

To increase the limit of the maximum upload size, you should edit your PHP configuration files:

1. Open the php.ini file. You can find it:

   - on Linux in /etc/php.ini
   - on Windows in c:\windows\php.ini

2. Set the required limits:

       post_max_size = 100MB
       upload_max_filesize = 100MB

3. Optionally, set the following parameters:

   - memory_limit
   - upload_tmp_dir
   - max_execution_time

To make sure that new settings are applied, use the phpinfo() function which outputs information about the current state of PHP.

### PHP

    <?php
    	phpinfo();
    ?>

### Configuring Apache Web Server

If you use the Apache web server, you should also edit the php.conf file:

1. Open the php.conf file. You can find it:

   - on Linux in /etc/httpd/conf.d/php.conf
   - on Windows in <Apache installation folder>\conf\php.conf

2. Change the LimitRequestBody parameter according to the post_max_size value, e.g.:

   LimitRequestBody 104857600

Do not forget to restart your server after modifying its configuration.

### Configuring IIS Web Server

If you use the IIS web server, you should follow one of the next configurations.

#### IIS 7 Configuration

1. Go to C:\Windows\System32\inetsrv\config\applicationHost.config and change

   ### XML

       <section name="requestFiltering" overrideModeDefault="Deny" />

   to:

   ### XML

       <section name="requestFiltering" overrideModeDefault="Allow" />

2. Add to your application's web.config the following sections:

   ### XML

       <system.webServer>
           <security>
               <requestFiltering>
                   <requestLimits maxAllowedContentLength ="2147482624" /> <!-- in bytes -->
               </requestFiltering>
           </security>
       </system.webServer>

   ### XML

       <system.web>
            <httpRuntime maxRequestLength="2097151"/> <!-- in kilobytes -->
       </system.web>

#### IIS 6 Configuration

Add to your application's web.config the following section:

### XML

    <system.web>
        <httpRuntime maxRequestLength="2097151"/> <!-- in kilobytes -->
    </system.web>

If you have URLScan installed and still experience this problem, go through the following steps:

1. Open the UrlScan.ini file which is typically located at C:\Windows\system32\inetsrv\urlscan folder.
2. Set the MaxAllowedContentLength key to the desired value (in bytes).
3. Save changes and restart IIS.

Do not forget to restart your server after modifying its configuration.
