+Add a photo.
+
+Because the pwg.images.add method is a bit complex (for reliability
+reasons), we propose a simpler method to add photos with Piwigo web API.
+
+## Authentication
+
+This method requires authentication with an administrator user.
+
+This method requires an HTTP POST request.
+
+## Parameters
+
+<u>**Important note**</u>: we are uploading a file, so the HTTP request
+encoding must be set to "form-data".
+
+| Key      | Example                  | Mandatory?    | Description                                                                                                                                      |

+| category | 123                      | **mandatory** | the identifier of the destination category, use pwg.categories.getList to find existing categories                                               |
+| name     | A nice title             | *optional*    | the title of your photo, don't make it too long (use the comment to go into details                                                              |
+| author   | Paul Nikanon             | *optional*    | the author of the photo                                                                                                                          |

+| level    | 2                        | *optional*    | (default = 0) privacy setting. See an example in your Piwigo on screen Administration \> Photos \> Add. 0 is for everybody, 8 is for admins only |
+| tags     | tag1, tags2, another tag | *optional*    | A list of coma separated tags to describe your photo. Missing tags are created automatically                                                     |
+
+## Photo Resize
+
+This method doesn't expect a "web size" photo. Piwigo will resize the
+photo if needed and create the thumbnail.
+
+As an administrator, you can set the resize settings on the
+<u>Administration \> Photos \> Add \> Settings</u> screen.
+
+If the photo is larger than maximum dimensions, then Piwigo will use
+your photo as a "high definition" photo and resize it for web display.
+
+## Example
+
+Here comes a full example in Perl languages:
+
+``` perl
+#!/usr/bin/perl
+
+use LWP::UserAgent;
+
+my %conf = (
+    base_url => 'http://piwigo.org/demo',
+);
+
+my $ua = LWP::UserAgent->new;
+$ua->cookie_jar({});
+
+$ua->post(
+    $conf{base_url}.'/ws.php',
+    {
+        method => 'pwg.session.login',
+        username => 'john',
+        password => 'NWgeWHjy8',
+    }
+);
+
+$ua->post(
+    $conf{base_url}.'/ws.php',
+    {
+        method => 'pwg.images.addSimple',
+        image => ['/home/john/photos/wild tiger.jpg'],
+        category => 4,
+        tags => 'tag1, tag2, another tag',
+        name => 'A nice title',
+        comment => 'A longer description',
+        author => 'Paul Nikanon',
+        level => 2,
+    },
+    'Content_Type' => 'form-data',
+);
