To make the news module customizable and expandable, you should think of putting in few tables instead of a single table.
NewsCategoryMaster
---------------------
NewsCategoryID (PK)
NewsCategory
NewsParentCategoryID (As Foreign key linking to the NewsCategoryID of the same table)

NewsMasterTable
-------------------
NewsID
NewsCategoryID
Title
Author
NewsDescription
PublishDate
IsActive
IsDeleted

Sounds like you are looking for a "Content Management System"

IF this is a course, talk to your teacher, you are very lost. If you're teaching yourself, buy a book and read it. If you're charging someone for this code, you are the worst kind of thief, and you should own up, because it's inevitable that this project will end in tears.

For the poor bugger (including you in a couple of months time) that will have to maintain this code, please name these things properly. Label49 or Label68 are not an acceptable names.

You are converting the value to a string, then comparing it with an integer. Why not keep both sides as integers or convert both sides to strings?

Something like this

if( DBNull.Value.Equals( dr["prod2"] ) || dr["prod2"].ToString() == "0")
    Label28.Visible = false;
else
    Label28.Text = dr["prod2"].ToString();

Using the wrong tool for the job is half the fun.

Don't call the ToString() before doing a NULL check. Do something like

if (dr["prod2"] != null)
{
    string prod2 = dr["prod2"].ToString();
    Label28.Visible = !(prod2 == "0");
    Label28.Text = prod2;
}

Right click on the cross image and check the path which is it taking. You can also view the source and check the path from which the image is mapped. It is preferred to set the image path dynamically in the code-behind with the fully qualified virtual path like shown below:

img1.Src = "http://localhost/demoapp/images/img_bak.gif";

You have to remove the image path from the image definition in aspx as well. Try to check what is the image url (virtual path) and then paste it into that code. Are you trying it in your localhost or somewhere else? If it is not in localhost then permission can be an issue. Just paste image path that you are specifying in the code, in the browser and check manually whether the image is getting displayed or not.

There is no foolish question, there is no final answer...
