hi diya...
its a trick.. see when you fetch the data from database to datatable or dataset then your photoid have the same index in datatable as in gridview... when you bind them
so find the index in datatable.. the same index will be in gridview. use  the index to set the GridView.PageIndex and bind the grid.. you grid will open the same photo that you pass in the URL. and by paging you can also navigate to other photos too...
hope you got it.

hi diya,
you can take simple gridview with set the attribute to page size="1" and allow paging="true"..... Implement its pageInex_changing and pageIndex_chagned event  like this: protected void grvCases_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
try
{
GridView1.PageIndex = e.NewPageIndex;
}
catch
{
GridView1.PageIndex = 0;
}
}
protected void grvCases_PageIndexChanged(object sender, EventArgs e)
{
BindGrid();
}
you can pass the imageid/PhotoId in QueryString and based on that get the index of the photo and then on page load set the grid index with that... here is BindGrid () method that bind the grid and set the index according to the image id
private void BindGrid()
{
GridView1.DataSource = CollectionPhoto.getPhotos(CID).DefaultView;
if (!Page.IsPostBack)
{
GridView1.PageIndex = getIndex(Imgid);
}
GridView1.DataBind();
lblCount.Text = CollectionPhoto.getPhotos(CID).RowCount.ToString();
}
Please mark as answer if it helps.
