    How can i display image 3 images in row using imageGen

    Hello everyone,

    I have been working on the gallery page to display sponsor image, I used imageGen package and created xslt to get image from Media item and create Marcros then add marcros to the template. How can i display image aliment to horizontal and display 3 images in the row  as image below  and xslt 

    <?xml version="1.0" encoding="UTF-8"?>

    <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>

    <xsl:stylesheet 

    version="1.0" 

    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 

    xmlns:msxml="urn:schemas-microsoft-com:xslt"

    xmlns:umbraco.library="urn:umbraco.library" xmlns:Examine="urn:Examine" 

    exclude-result-prefixes="msxml umbraco.library Examine ">

    <xsl:output method="xml" omit-xml-declaration="yes"/>

    <xsl:param name="currentPage"/>

        <xsl:variable name="mediaFolderId" select="number($currentPage/mediaFolderId)" />

        <xsl:variable name="thumbWidth" select="number(256)" />

        <xsl:variable name="thumbHeight" select="number(170)" />

        <xsl:template match="/">

            <!-- Displays all images from a folder in the Media Library -->

            <xsl:if test="number($mediaFolderId)">

                <ul id="gallery">

                    <xsl:for-each select="umbraco.library:GetMedia($mediaFolderId, true())/Image">

                       <xsl:if test="umbracoFile !=''">                        <li>

                                <a href="{umbracoFile}" title="{@nodeName}" rel="gallery">

                 <img src="/imageGen.ashx?image={umbraco.library:UrlEncode(umbracoFile)}&amp;width=         {$thumbWidth}&amp;height={$thumbHeight}" width="{$thumbWidth}" height="{$thumbHeight}" alt="{@nodeName}" title="{@nodeName}" class="thumbnail" />

                               </a>

                            </li>

                        </xsl:if>

                    </xsl:for-each>

                </ul>

            </xsl:if>

    </xsl:template>

    </xsl:stylesheet>

    And  This question might be silly question , How can i add  lightweight jQuery plugin  to my project? 

    Thank you in advance,

    Amp.

    Hi Maiyana

    Depending on which jQuery plugin you want to use in your project, there are several solutions to build the gallery. But I based a solution on your example and showed how you can combine it with e.g. Fancybox v.2

    I have modified the xslt a bit:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
    <xsl:stylesheet 
        version="1.0" 
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
        xmlns:msxml="urn:schemas-microsoft-com:xslt"
        xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" xmlns:Examine="urn:Examine" xmlns:ucomponents.cms="urn:ucomponents.cms" xmlns:ucomponents.dates="urn:ucomponents.dates" xmlns:ucomponents.email="urn:ucomponents.email" xmlns:ucomponents.io="urn:ucomponents.io" xmlns:ucomponents.media="urn:ucomponents.media" xmlns:ucomponents.members="urn:ucomponents.members" xmlns:ucomponents.nodes="urn:ucomponents.nodes" xmlns:ucomponents.random="urn:ucomponents.random" xmlns:ucomponents.request="urn:ucomponents.request" xmlns:ucomponents.search="urn:ucomponents.search" xmlns:ucomponents.strings="urn:ucomponents.strings" xmlns:ucomponents.urls="urn:ucomponents.urls" xmlns:ucomponents.xml="urn:ucomponents.xml" 
        exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets Examine ucomponents.cms ucomponents.dates ucomponents.email ucomponents.io ucomponents.media ucomponents.members ucomponents.nodes ucomponents.random ucomponents.request ucomponents.search ucomponents.strings ucomponents.urls ucomponents.xml ">
    
    
    <xsl:output method="xml" omit-xml-declaration="yes"/>
    
    <xsl:param name="currentPage"/>
    
    <xsl:variable name="mediaFolderId" select="number($currentPage/gallery)" />
    <xsl:variable name="thumbWidth" select="number(256)" />

        <xsl:variable name="numberOfImages" select="count($images)" />
            <xsl:variable name="numberOfColumns" select="3" />
    
            <ul id="gallery">
                <xsl:for-each select="$images">
    
                    <!-- Calculate the total number of rows -->
                    <xsl:variable name="rows" select="ceiling($numberOfImages div $numberOfColumns)" />
                    <!-- current column -->

                        <xsl:value-of select="$colcount"/>
                        <xsl:text> row</xsl:text>
                        <xsl:value-of select="$rowcount" />
                        <xsl:if test="$rowcount = 1">
                          <xsl:text> firstRow</xsl:text>
                        </xsl:if>
                        <xsl:if test="$rowcount = $rows">

                          <xsl:when test="$rowcount mod 2 = 0">
                            <xsl:text> rowEven</xsl:text>
                          </xsl:when>
                          <xsl:otherwise>
                            <xsl:text> rowOdd</xsl:text>
                          </xsl:otherwise>
                        </xsl:choose>
                        <xsl:choose>
                          <xsl:when test="$colcount mod 2 = 0">
                            <xsl:text> colEven</xsl:text>
                          </xsl:when>
                          <xsl:otherwise>
                            <xsl:text> colOdd</xsl:text>
                          </xsl:otherwise>
                        </xsl:choose>
                    </xsl:variable>
    
                    <xsl:if test="umbracoFile !=''">
                        <li>
                            <xsl:attribute name="class">
                              <xsl:value-of select="$class" />
                            </xsl:attribute>
                            <a href="{umbracoFile}" title="{@nodeName}" class="fancybox" rel="gallery">
                                <img src="/imageGen.ashx?image={umbraco.library:UrlEncode(umbracoFile)}&amp;width={$thumbWidth}&amp;height={$thumbHeight}" width="{$thumbWidth}" height="{$thumbHeight}" alt="{@nodeName}" title="{@nodeName}" class="thumbnail" />
                            </a>
                        </li>
                    </xsl:if>
                </xsl:for-each>
            </ul>
        </xsl:if>
    
    </xsl:template>
    
    </xsl:stylesheet>

    Some of the additional classes added to <li> tag are not necessary and depending on your need you could exclude them. Sometimes it might be useful when you add margin-left: 10px; in css, but you don't want the last column to have margin to the left. However with CSS3 :nth-child() Selector this could be done just with css.. 

    Besides the xslt I have included the files from Fancybox in /css and /scripts folder and have a simple template like this:

    <%@ Master Language="C#" MasterPageFile="~/umbraco/masterpages/default.master" AutoEventWireup="true" %>
    
    <asp:Content ContentPlaceHolderID="ContentPlaceHolderDefault" runat="server">
    <!doctype html>
    <html>
    <head>
        <meta charset="UTF-8">
        <title>Gallery</title>
        <link rel="stylesheet" href="/css/jquery.fancybox.css?v=2.1.5" type="text/css" media="screen" />
        <link rel="stylesheet" href="/css/gallery.css" type="text/css" media="screen"/>
    </head>
    <body>
        <h1>Gallery</h1>
        <umbraco:Macro Alias="Gallery" runat="server"></umbraco:Macro>
    
        <!-- Add jQuery library -->
        <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
    
        <!-- Add mousewheel plugin (this is optional) -->
        <script type="text/javascript" src="/fancybox/lib/jquery.mousewheel-3.0.6.pack.js"></script>
    
        <!-- Add fancyBox -->
        <script type="text/javascript" src="/scripts/fancybox/jquery.fancybox.pack.js?v=2.1.5"></script>
    
        <script type="text/javascript">
            $(document).ready(function() {
                $(".fancybox").fancybox();
            });
        </script>
    </body>
    </html>
    </asp:Content>

    Notice that jQuery and Fancybox script is included before fancybox is called and it's used on the element with class="fancybox" .. you can just rename it to something else if you want to..

    Finally I have some very basic styling, nothing fancy :)

    body { font-family: Arial, sans-serif; color: #333; }
    h1 { margin-left: 20px; }
    ul#gallery {
        float: left;
        list-style: none;
        margin: 10px;
        padding: 0;
        width: 828px;
    }
    
    ul#gallery li {
        float: left;
        margin: 10px;
    }

    That's it..

    Now we have a simple image gallery with a jQuery plugin. There are plenty other lightweight jQuery galleries out there e.g. Lightbox2 but are use in a simular way..
    Here is how it looks:

    I'm glad you find it useful :)

    This part you could of course extend with the configurations the FancyBox.. or another plugin is using..

    <script type="text/javascript">
            $
    (document).ready(function(){
                $
    (".fancybox").fancybox();
           
    });
    </script>

    and it might be suitable to place that code in a seperate javascript file...
