When you want to change the new SharePoint 2013 default browse tab (image 1) with the AD tab (image 2) showing below, you need to do the following:
image 1: default browse tab
image 2: AD image browse tab
1. Create a new master page by copying seattle.master as the template
2. Find the first div with id=”siteIcon“ by adding the style=”display:none;” to hidden the default logo.
3. Find the 2nd div <div class=”ms-breadcrumb-box ms-tableCell ms-verticalAlignTop“>then add your AD image tags or javascript to display the image. If you have a customized image control for rotating images from a document library, add it here:
<Kproject:RotatingImage runat=”server” TagName=”div” ImageLibraryNameKey=”SplashMasterPage.BannerImage.PictureLibraryName” ImageURLKey=”SplashMasterPage.BannerImage.PictureLibraryPath“/>
If the control uses the background image for a div to display the AD image, remember doing the following code to center the image with no repeat:
base.Style.Add(HtmlTextWriterStyle.BackgroundImage, this.image.ImageUrl);
base.Style.Add(“background-repeat”, “no-repeat”);
base.Style.Add(“background-position-x”, “center”);
base.Style.Add(HtmlTextWriterStyle.Height, “100px”);
base.Style.Add(HtmlTextWriterStyle.Width, “100%”);
4. Find other div that display the breadcrmb and title to hidden them:
<div class=”ms-breadcrumb-top” style=”display:none;”>
<div class=”ms-breadcrumb-dropdownBox“ style=”display:none;”>
<h1 id=”pageTitle“ class=”ms-core-pageTitle“ style=”display:none“>
5. Find the 3rd div to give the max with in 1 or 1 pix instead hidden them. Hidden this div will not center the image. Also hidden the search area or move it to the location in your new layout:
<div class=”ms-tableCell ms-verticalAlignTop“ style=”max-width:2px;”>
<asp:ContentPlaceHolder id=”PlaceHolderSearchArea“ runat=”server” Visible=”false”>
<div id=”searchInputBox“ style=”display:none“>
<SharePoint:DelegateControl runat=”server” ControlId=”SmallSearchInputBox“ Visible=”false” />
</div>
</asp:ContentPlaceHolder
