I have a image scroll web part in SharePoint 2010, how do i enlarge the image, when a user clicks on the image.(Something like, when you google a image, and when you click on particular image, the image gets enlarged and the page becomes blurred.

the images are coming from the sharepoint picture lib.

here is what i am using for image scroll.

What I have tried:

<div style="width:auto; height:400px; overflow:hidden; ">
   
   <marquee style="height:350px;overflow:hidden"  direction="up" >
        
        <asp:Literal ID="ltrImage" runat="server">        
</marquee>
</div>

code behind:

using (SPSite site = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList PicLib = web.Lists.TryGetList("ImageScroll");
                    string Image = "<table>";
                                        SPListItemCollection listcol = PicLib.Items;
                    foreach (SPListItem item in listcol)
                    {

                       
                        Image += "<tr><td><img src='" + web.Url + "/" + item.Url + "' style='height:auto;width:350px;'/></td></tr>";

                    
                    }

                    //Title1 += "</table>";
                    Image += "";
                    ltrImage.Text = Image;


                }
            }

After your loop you are setting Image back to an empty string before you assign it to your ltrImage.Text. What you should be doing is adding your table to the innerHTML of a div tag instead of the text property. Have a look below at the changes to your code and markup.

<div style="width:auto; height:400px; overflow:hidden; ">
   
   <marquee style="height:350px;overflow:hidden"  direction="up" >
        
        <div id="ltrImage" runat="server"></div>     
</marquee>
</div>

using (SPSite site = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList PicLib = web.Lists.TryGetList("ImageScroll");
                    string Image = "<table>";
                                        SPListItemCollection listcol = PicLib.Items;
                    foreach (SPListItem item in listcol)
                    {                        
                        Image += "<tr><td><img src="" + web.Url + "/" +      item.Url + "" style="height:auto;width:350px;" /></td></tr>                    
                    }                    
                    ltrImage.innerHTML = Image; 
                }
            }</table>

Also notice how I closed the tag at the end. There is a better way to code that, but this should at least get you going.
