This post is about rotating images with fixed captions in SharePoint Foundation 2010. There are a few posts around which talks about gettting it done but doesn't work properly so thought to write a step-by-step blog on it.
Note: You can also rotate images using Content query web part (
link), but for that you should have SharePoint Server 2010, as content query web part doesn't come with SharePoint foundation 2010!
Requirements:
- Download
jquery-1.7.2.min.js
- Download
captify.tiny.js (for fixed caption)
- Create a picture library or use the default one and put some pictures into it.
Keep both JQuery files in the <14 hive>\Templates\Layouts\JQuery (create this folder if doesn't exist)
1. Create a new site page.
2. Now edit page in normal mode in SharePoint designer. Put your cursor before SPAN tag with id 'layoutsData' and insert an Empty Data View.
Switch to 'Split' mode, click 'Click here to select a data source' and select the picture library.
Select 'Title' for image caption and 'URL Path' for link to image. Now insert selected fields as multiple item view. It will insert complete xslt required for rendering the picture library on page.
Switch to 'Code' view. Automatically generated code contains few XSLT tag which are of no use in our case so I have removed these. Select automatically generated <XSL> tag and overwrite it with the <XSL> tag given below.

Note : For your information, I have
highlighted the text which is inserted after cleaning the xslt code.
Done! Just save the page and navigate to it. You should be able to see images fadding in with a regular interval having fixed caption.
Additional Notes : You can also filter the images/items by providing required filter criteria in this tag:
<xsl:variable name="Rows" select="/dsQueryResponse/Rows/Row
[<filter_criteria>]"/>
Please let me know if you have any query.
