A survey of the possibilities to call, extend and modify galleries with the code in the content item.

The "Very Simple Image Gallery" Plugin is called from within the content item. The code used offers - beside of setting the folder with the images - additional possibilities to enhance and arrange the gallery.

A.) Gallery

The code consists of the call {*vsig}{/vsig*} (without the asterisks) and contains the name of the folder with your images. The configured path to this folder (image root, by default "/images/stories" in Joomla!1.5 or "/images/" in Joomla!1.6/1.7) is added by the plugin automatically and must not be inserted.

The complete call in our sample would look such as:

{*vsig}verysimple{/vsig*} - without the asterisks

To use a folder within a folder, the path below the set root folder is used, e. g. to use the folder /images/stories/folder/subfolder" the call in Joomla!1.5 would look such as:

{*vsig}folder/subfolder{/vsig*} - without the asterisks

In general that´s it and the gallery is ready to go.

B.) Parameter Overrides

Starting with version 1.3.0 the "Very Simple Image Gallery" offers the possibility to change almost every default setting from the backend whilst calling the plugin within the content item. With this feature it is possible to use different settings for every single gallery. One may change the position of the thumbnails, the width of the gallery, if to show captions and/or links and so on.

To achieve this, the call of the plugin gets extended by the needed parameters. They are separated from the folder name and from each other by vertical bars (|). The have the syntax PARAMETER=VALUE:

List of possible parameters:

width - width of the whole gallery in pixel (integer) e.g.: 600

height - maximum height of the images set in pixel; possible values: empty (use full width), (integer) e.g.: 300

imquality - quality of images in percent (integer from 1-100) e.g.: 90

align - align the gallery within the content item; possible values: 0 (right), 1 (center), 2 (left), 3 (float left), 4 (float right)

twidth - width of thumbnails in pixel (integer) e.g.: 80

area - no longer used (version 1.6.5)

cols - thumbnail columns left/right of main image (integer) e.g.: 2

sort - images sort order; possible values: 0 (A-Z - DEFAULT), 1 (Z-A), 2 (old-new), 3 (new-old), 4 (random)

sets - number of thumbnails to show per set; possible values "empty" (all images), any integer

cfwd - value for control-element "next"; possible values "empty" (default button), any text, filename of button (refer to Plugin Howto)

cbwd - value for control-element "prev"; possible values "empty" (default button), any text, filename of button (refer to Plugin Howto)

caps - show captions; possible values: 0 (no), 1 (yes)

links - show links; possible values: 0 (no), 1 (yes)

autolink - link the main image to the original image file; possible values: 0 (no), 1 (yes)

Samples:

{*vsig}verysimple|width=600|right=2{/vsig*} - without the asterisks
Regardless of the settings in the backend, this gallery is shown with a width of 600 pixel (width=600). The thumbnails are below the main image and get justified to the right border of the main image (right=2)

{*vsig}verysimple|width=600|right=1|cols=2{/vsig*} - without the asterisks
Width 600 pixel (width=600), thumbnails right (right=1), in two columns (cols=2)

{*vsig}verysimple|twidth=80|theight=60|space=3|quality=80{/vsig*} - without the asterisks
Thumbnails are 80 pixel of width (twidth=80), 60 pixel of height (theight=60), there is 3 pixel space between them (space=3) and they are generated with 80% of the possible quality (quality=80)

Notice:

The parameters listed here correspond with the parameters in the plugins configuration panel. Find a details description at: Howto Plugin .
The first parameter of the initial call always has to be the folder name (path). The sorting of the other parameters is arbitrarily.

C.) Captions

Captions and text have there own call. It´s:

{*vsig_c}gallery-number|imagefile|caption|text{/vsig_c*} - without the asterisks

Gallery-number:
The galleries within one content item are numbered automatically by the plugin according their appearance in the article starting with 0.
This setting is obligatory.

Imagefile:
The exact name of the file "myimage.jpg".
Left empty, the call is used as default for the whole gallery. This means, if there is no setting for an image, this one is used.

Caption:
The Caption. If left empty . . . no caption is shown.

Text:
The additional text below the caption. If left empty . . . no text is shown.

Samples:

{*vsig_c}0||myTitel|myText{/vsig_c*} - without the asterisks
This call sets "myTitel" and "myText" as the default values for the first gallery within the current content item by leaving the imagefile-value empty.
Notice: You don´t have to set a Default. If you don´t and there is no setting for an image, just nothing is shown.

{*vsig_c}1|pic01.png||myText{/vsig_c*} - without the asterisks
pic01.png of the second gallery in the content item has no caption but the text "myText"

{*vsig_c}0|pic02.png||{/vsig_c*} -without the asterisks
pic02.png in the first gallery shows no caption and no text although there is a default. The explicit setting overrides it.

{*vsig_c}0|pic05.jpg|myTitelA|myTextA{/vsig_c*} - without the asterisks
{*vsig_c}0|pic06.jpg|myTitelB|myTextB{/vsig_c*} - without the asterisks
{*vsig_c}0|pic07.jpg|myTitelC|myTextC{/vsig_c*} - without the asterisks
{*vsig_c}0|pic08.jpg|myTitelD|myTextD{/vsig_c*} - without the asterisks . . . and so on

Notice:
If you don't want to show captions, you may use them to set the attributes "alt" and "title" of your images. If the plugin finds a set caption for an image, it uses the title-line for ALT/TITLE of the image even when captions are not activated.

It is of no importance where within your content item and in which order your setting are.
The number of parameters has always to be 4. This means, a call always must contain 3 vertical bars, even if a setting is empty (e.g. the image file).
These vertical bars are protected characters within the calls and may not be used within your values.

D.) Links

If we want to link the images of our gallery, there is a third call to do so:

{*vsig_l}gallery-number|imagefile|URL|titel|target{/vsig_l*} - without the asterisks

Gallery-number:
The galleries within one content item are numbered automatically by the plugin according their appearance in the article starting with 0.
This setting is obligatory.

Imagefile:
The exact name of the file "myimage.jpg".
Left empty, the call is used as default for the whole gallery. This means, if there is no setting for an image, this one is used.

URL:
The URL you want to link the image with. e.g.: http://www.bretteleben.de

Titel:
The titel, shown when the mouse is over the image. e.g.: bretteleben.de

target:
The window, you want to open the linked URL. e.g.: _blank (new window), _self (same window)

Samples:

{*vsig_l}0||http://www.bretteleben.de|bretteleben.de|_blank{/vsig_l*} - without the asterisks
This call sets a default link for the first gallery within the current content item by leaving the value for the image file empty. The link opens in a new window.

{*vsig_l}1|pic01.png|http://www.disney.com|Disney|_self{/vsig_l*} - without the asterisks
pic01.png in the second gallery within the content item is linked to www.disney.com. The link opens in the current window.

{*vsig_l}0|pic02.png|||{/vsig_l*} -without the asterisks
We don´t want pic02.png in the first gallery within the content item to be linked. A special case, because as soon as we have links within a gallery, every image gets linked. Setting this empty call the image is linked to the current page, without any further setting.

{*vsig_l}0|pica.jpg|http://www.my.domain.com/myGreatProduct1|greatProduct1|_self{/vsig_l*} - without the asterisks
{*vsig_l}0|picb.jpg|http://www.my.domain.com/myGreatProduct2|greatProduct2|_self{/vsig_l*} - without the asterisks
{*vsig_l}0|picc.jpg|http://www.my.domain.com/myGreatProduct3|greatProduct3|_self{/vsig_l*} - without the asterisks
{*vsig_l}0|picd.jpg|http://www.my.domain.com/myGreatProduct4|greatProduct4|_self{/vsig_l*} - without the asterisks ... and so on

Notice:
It is of no importance where within your content item and in which order your setting are.
The number of parameters has always to be 5. This means, a call always must contain 4 vertical bars, even if a setting is empty (e.g. the imagefile).
These vertical bars are protected characters within the calls and may not be used within your values.
