Embedding an Image within a user control

Hello Experts,

I found the following code on the website http://www.codeproject.com. The author Manny Salazar designed this code to be a user control that provides a custom pager for the GridView control.

This code is compiled into a DLL and placed in the bin folder for the website.

I want to modify the code to use images in place of the"First", "Next", "Previous", and "Last" LinksButtons.

protected override void InitializePager
    (GridViewRow row, int columnSpan, PagedDataSource pagedDataSource)
{
    if (PagerType == ThisPagerType.Regular)
    {
        // if PagerType is not DropDownList
        // render the regular GridView Pager
        base.InitializePager(row, columnSpan, pagedDataSource);
    }
    else
    {
        TableCell cell_1;
        // if we are going to use dropdownlist
        if (PagerType == ThisPagerType.DropDownList)
        {
            // our Pager with DropDownList control

            // create our DropDownList control
            DropDownList ddl = new DropDownList();
            // populate it with the number of Pages of our GridView
            for (int i = 0; i < PageCount; i++)
            {
                ddl.Items.Add(new ListItem(Convert.ToString(i + 1), i.ToString()));
            }
            ddl.AutoPostBack = true;
            // assign an Event Handler when its Selected Index Changed
            ddl.SelectedIndexChanged += new EventHandler(ddl_SelectedIndexChanged);
            // synchronize its selected index to GridView's current PageIndex
            ddl.SelectedIndex = PageIndex;

            // add our first TableCell which will contain the DropDownList
            cell_1 = new TableCell();

            // we just add a Label with 'Page ' Text
            cell_1.Controls.Add(PageOf());

            // our DropDownList control here.
            cell_1.Controls.Add(ddl);

            // and our Total number of Pages
            cell_1.Controls.Add(PageTotal());
        }
        else
        {
            // if we are going to use the FirstPrevNextLast buttons.
            LinkButton first = new LinkButton();
            first.Text = "First ";
            // first button will always have a value of zero (0)
            first.CommandArgument = "0";
            first.Enabled = PageIndex > 0;
            // add click event handler
            first.Click += new EventHandler(navigate_Click);

            LinkButton prev = new LinkButton();
            prev.Text = "Prev ";
            // set Prev button arguments to current PageIndex minus 1
            prev.CommandArgument = string.Format("{0}", (PageIndex - 1));
            prev.Enabled = (PageIndex > 0);
            prev.Click += new EventHandler(navigate_Click);

            LinkButton next = new LinkButton();
            next.Text = "Next ";
            // set Next button arguments to current PageIndex plus 1
            next.CommandArgument = string.Format("{0}", (PageIndex + 1));
            next.Enabled = (PageIndex < (PageCount - 1));
            next.Click += new EventHandler(navigate_Click);

            LinkButton last = new LinkButton();
            last.Text = "Last";
            // Last button will always have a value equal to PageCount minus 1
            last.CommandArgument = string.Format("{0}", (PageCount - 1));
            last.Enabled = (PageIndex < (PageCount - 1));
            last.Click += new EventHandler(navigate_Click);

            cell_1 = new TableCell();

            // add the First button to cell controls collection
            cell_1.Controls.Add(first);
            // add the Prev button
            cell_1.Controls.Add(prev);
            // add the Next button
            cell_1.Controls.Add(next);
            // add the Last button
            cell_1.Controls.Add(last);
        }

        Table tbl = new Table();
        tbl.BorderWidth = 0;
        tbl.Width = Unit.Percentage(100);
        // add one TableRow to our Table
        tbl.Rows.Add(new TableRow());

        // the 2nd TableCell will display the Record number you are currently in.
        TableCell cell_2 = new TableCell();
        cell_2.Controls.Add(PageInfo(pagedDataSource.DataSourceCount));

        // add now the 2 cells to our created row
        tbl.Rows[0].Cells.Add(cell_1);
        tbl.Rows[0].Cells.Add(cell_2);
        tbl.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Left;
        tbl.Rows[0].Cells[1].HorizontalAlign = HorizontalAlign.Right;

        // in Pager's Row of our GridView add a TableCell
        row.Controls.AddAt(0, new TableCell());
        // sets it span to GridView's number of columns
        row.Cells[0].ColumnSpan = Columns.Count;
        // finally add our created Table
        row.Cells[0].Controls.AddAt(0, tbl);
    }

I have four .gif(s) that I want to use in the following part of the code:

     else
        {
            // if we are going to use the FirstPrevNextLast buttons.
            LinkButton first = new LinkButton();
            first.Text = "First ";
            // first button will always have a value of zero (0)
            first.CommandArgument = "0";
            first.Enabled = PageIndex > 0;
            // add click event handler
            first.Click += new EventHandler(navigate_Click);

            LinkButton prev = new LinkButton();
            prev.Text = "Prev ";
            // set Prev button arguments to current PageIndex minus 1
            prev.CommandArgument = string.Format("{0}", (PageIndex - 1));
            prev.Enabled = (PageIndex > 0);
            prev.Click += new EventHandler(navigate_Click);

            LinkButton next = new LinkButton();
            next.Text = "Next ";
            // set Next button arguments to current PageIndex plus 1
            next.CommandArgument = string.Format("{0}", (PageIndex + 1));
            next.Enabled = (PageIndex < (PageCount - 1));
            next.Click += new EventHandler(navigate_Click);

            LinkButton last = new LinkButton();
            last.Text = "Last";
            // Last button will always have a value equal to PageCount minus 1
            last.CommandArgument = string.Format("{0}", (PageCount - 1));
            last.Enabled = (PageIndex < (PageCount - 1));
            last.Click += new EventHandler(navigate_Click);

            cell_1 = new TableCell();

            // add the First button to cell controls collection
            cell_1.Controls.Add(first);
            // add the Prev button
            cell_1.Controls.Add(prev);
            // add the Next button
            cell_1.Controls.Add(next);
            // add the Last button
            cell_1.Controls.Add(last);
        }

I am assuming that's where I would substitute the images for the text. If anyone could help me figure this out that would be great.

I want to embed the images in the dll so that the user doesn't have to worry about where the images are.

As a further enhancement I wanted to embed a css file. Is that possible and if so how?

Thanks.
