Cette étape consiste à gérer les fichiers multimedia que vous avez transférés dans le répertoire de votre site phpGedView réservé aux media.

Le chemin de ce répertoire est déterminé dans le menu de configuration de votre Gedcom (Mon portail --> Gérer les fichiers gedcom --> Fichier de configuration --> modifier) , dans la rubrique "objets multimedia", sous-rubrique "Répertoire MultiMedia". Par défaut, il s'agit du répertoire "/media" qui est placé directement à la racine du répertoire d'installation de votre site phpGedView.

En tant qu'administrateur vous pouvez créer une arborescence de répertoires pour organiser vos fichiers multimedia. En créant des répertoires à partir de cette page, celà vous garantit que les répertoires dédiés aux vignettes (thumbnails) seront créés automatiquement ainsi qu'un fichier index.php dans chacun de ces répertoires.

Vous pouvez déplacer un objet multimedia dans la structure des répertoires en utilisant le lien "Modifier" qui se situe dans le menu à gauche de chaque objet multimedia. La vignette est également déplacée automatiquement, conservant ainsi toute la cohérence au répertoire de vos objets multimedia.

Si vous n'avez pas transféré les fichiers correspondant aux vignettes de vos objets multimedia ou si vous avez oublié de cocher la case "vignette automatique", vous avez toujours la possibilité de créer des vignettes à partir de cette page. Cochez la case "Montrer les vignettes"; si une vignette n'apparaît pas, vous devez alors cliquer sur le lien "vignette automatique" pour en créer une.

Filtre

L'option filtre est constituée de trois parties.

• Saisie de l'information:- c'est dans cette case vide que vous entrez l'information sur laquelle vous voulez que le filtre soit appliqué. Le filtre est INSENSIBLE aux majuscules/minuscules qui sont saisies.
• Bouton filtre:- ce bouton actionne le filtre
• Bouton reset:- ce bouton efface tous les filtres qui ont été actionnés par l'utilisateur

Upload Media Files

This option allows you to upload multiple files (maximum of five) at one time. These files will be uploaded with a minmum amount of information in relation to them and links to individuals, families and other locations will have to be made after the upload process is completed.

Note: The selection window indicates the maximum file size that can be uploaded . In this case it indicates 100M - most times it will be much smaller.

The use of folder names will depend upon your settings in the Multimedia section for your GEDCOM file. If this depth is set to 0 then folder names should not be used. The folder names you specify will be appended to media/. For example, media/myfamily. These folders should exist before attempting to upload files to them.

If a thumbnail has been created for the file you can also indicate the location of that file. This file will be placed in the appropriate thumbnail directory. The system can also create thumbnails on uploading if your computer system has had appropriate software installed to do this.

Clicking on Browse will open a window where the file you which to upload can be identified.

Adding multimedia files (MM) to the GEDCOM is a very nice feature. Although this program already has a great look without media, if you add pictures or other MM to your relatives, it will only get better.

What you should understand about Multimedia Files

There are many formats of Multimedia. Although PhpGedView can handle most of them, there some things to consider.

Formats

Pictures can be edited and saved in many formats. For example, .jpg, .png, .bmp, .gif, etc. If the same original picture was used to create each of the formats, the viewed image will appear to be the same size no matter which format is used. However, the image files stored in the database will vary considerably in size. Generally, .jpg images are considered to be the most efficient in terms of storage space.

Image Size

The larger the original image, the larger will be the resultant file's size. The picture should fit on the screen without scrolling; the maximum width or height should not be more than the width or height of the screen. PhpGedView is designed for screens of 1024x768 pixels but not all of this space is available for viewing pictures; the picture's size should be set accordingly. To reduce file sizes, smaller pictures are more desirable.

Resolution

The resolution of a picture is usually measured in "dpi" (dots/inch), but this is valid only for printed pictures. When considering pictures shown on screen, the only correct way is to use total dots or pixels. When printed, the picture could have a resolution of 150 - 300 dpi or more depending on the printer. Screen resolutions are rarely better than 50 pixels per inch. If your picture will never be printed, you can safely lower its resolution (and consequently its file size) without affecting picture quality. If a low-resolution picture is printed with too great a magnification, its quality will suffer; it will have a grainy appearance.

Color Depth

Another way to keep a file small is to decrease the number of colors that you use. The number of colors can differ from pure black and white (two colors) to true colors (millions of colors) and anything in between. You can see that the more colors are used, the bigger the size of the files.

Why is it important to keep the file size small?

• First of all, usually your webspace is limited. The more large files there are, the more web space you need on the server. The more space you need, the higher your costs.

• Bandwidth. The more data your server has to send to the remote location, the more you may have to pay to you ISP. Data throughput is a key area where ISPs and cost is normally apportioned according to the amount of data your server sends and receives.

• Download time. If you have large files, the user (also you) will have to wait for a long time for the page to download from the server.

How to upload your MM

There are two ways to upload media to the site. If you have a lot of media items to upload you should contact the site administrator to discuss the best ways. If it has been enabled by your site administrator, you can use the Upload Media form under your MyGedView menu. You can also use the Upload option on the Multimedia form to upload media items.

Generate Thumbnails

We have detected that your system has the ability to automatically generate thumbnails for certain types of images. There may be support for JPG, GIF, and PNG files. The types that your system supports are listed beside the checkbox.

By clicking this checkbox, you signal the system that you are uploading images of this type and that you want it to try to generate thumbnails for them. Leave the box unchecked if you want to provide your own thumbnails.
