How to set link on images with SP OOTB picture library slide show web part?

Question

I added a link column in my picture library and populated with links. Then added SP OOTB picture library slide show web part. Both pictures and it's description are showing. I need the link to be on the image so when user click on image it goes to whatever I put in the link field.

Answer 1

This is not OOTB functionality of the slide show webpart. To accomplish this behaviour you can extend the webpart to add the functionality or you can set the link with jQuery/SPServices.

Answer 2

Picture Library SlideShow web part class is marked a sealed, so there is no way to extend it.

But it could be customized on the client side, the solution description is presented below.

Load custom Picture Library fields

The following fields are loaded via SPQuery from Picture Library in Picture Library SlideShow web part:

• Title - picture title
• Description - picture description
• EncodedAbsWebImgUrl – Url of web image is used for displaying picture
• EncodedAbsUrl – Url of original image is used for picture link
• ImageWidth – picture width
• ImageHeight – picture height

So, in order to specify custom field for picture link we need to load it also. Loading of additional fields could happen during Slideshow initialization on the client side.

Specify custom field value for picture link

After custom fields are loaded, we need only to modify custom picture link values.
To accomplish it we will override JavaScript function for initializing picture.

The code below demonstrates how to override ShowPic function that is used for initializing picture in SlideShow:

<script type="text/javascript">


function SlideshowObjectInitializer() {

  ShowPic = (function(ShowPicOrig) {
      return function() {

           var ssObj = arguments[0];  //SlideShow object
           var curPicIdx=ssObj.index; //current picture index

           ShowPicOrig.apply(this, arguments); //call original ShowPic


           ssObj.link.href = '';  //<--put your custom picture link url here 

      };
  })(ShowPic);

}  


ExecuteOrDelayUntilScriptLoaded(SlideshowObjectInitializer, 'imglib.js');
</script>
