![](\"large_image.jpg\")
\n```\n\nIf you have a set of related items that you would like to group,\nadditionally include a group name in the `rel` (or `data-fancybox-group`) attribute:\n\n```html\n![](\"large_1.jpg\")
\n![](\"large_2.jpg\")
\n```\n\nInitialise the script like this:\n\n```html\n\n```\n\nMay also be passed an optional options object which will extend the default values. Example:\n\n```html\n\n```\n\nTip: Automatically group and apply fancyBox to all images:\n\n```js\n$(\"a[href$='.jpg'],a[href$='.jpeg'],a[href$='.png'],a[href$='.gif']\").attr('rel', 'gallery').fancybox();\n```\n\nScript uses the `href` attribute of the matched elements to obtain the location of the content and to figure out content type you want to display.\nYou can specify type directly by adding classname (fancybox.image, fancybox.iframe, etc) or `data-fancybox-type` attribute:\n\n```html\n//Ajax:\nExample\n//or\nExample\n\n//Iframe:\nExample\n\n//Inline (will display an element with `id=\"example\"`)\nExample\n\n//SWF:\nExample\n\n//Image:\nExample\n```\n\nNote, ajax requests are subject to the [same origin policy](http://en.wikipedia.org/wiki/Same_origin_policy).\nIf fancyBox will not be able to get content type, it will try to guess based on 'href' and will quit silently if would not succeed.\n(this is different from previsous versions where 'ajax' was used as default type or an error message was displayed).\n\nAdvanced\n--------\n\n### Helpers\n\nHelpers provide a simple mechanism to extend the capabilities of fancyBox. There are two built-in helpers - 'overlay' and 'title'.\nYou can disable them, set custom options or enable other helpers. Examples:\n\n```js\n//Disable title helper\n$(\".fancybox\").fancybox({\n helpers: {\n title: null\n }\n});\n\n//Disable overlay helper\n$(\".fancybox\").fancybox({\n helpers: {\n overlay : null\n }\n});\n\n//Change title position and overlay color\n$(\".fancybox\").fancybox({\n helpers: {\n title : {\n type : 'inside'\n },\n overlay : {\n css : {\n 'background' : 'rgba(255,255,255,0.5)'\n }\n }\n }\n});\n\n//Enable thumbnail helper and set custom options\n$(\".fancybox\").fancybox({\n helpers: {\n thumbs : {\n width: 50,\n height: 50\n }\n }\n});\n```\n\n### API\n\nAlso available are event driven callback methods. The `this` keyword refers to the current or upcoming object (depends on callback method). Here is how you can change title:\n\n```js\n$(\".fancybox\").fancybox({\n beforeLoad : function() {\n this.title = 'Image ' + (this.index + 1) + ' of ' + this.group.length + (this.title ? ' - ' + this.title : '');\n\n /*\n \"this.element\" refers to current element, so you can, for example, use the \"alt\" attribute of the image to store the title:\n this.title = $(this.element).find('img').attr('alt');\n */\n }\n});\n```\n\nIt`s possible to open fancyBox programmatically in various ways:\n\n```js\n//HTML content:\n$.fancybox( 'Lorem lipsum
