header image

Sorry? What do you mean by “for a certain age”?

I am sorry there is misspelling. I mean featured image for certain page.
The featured image allows you to add a header image for every page according to your content as mr. Morten Rand-Hendriksen explains in lynda.com for his tutorial website petal flowers.

That was Twenty Eleven theme – not Twenty Twelve.

Whatever, my question was that I wanted to make header image with 2012 theme. Can I do it?
When I upload header image, I can not see it in the home page. What is the solution

You can upload a new header image via Appearance -> Header.

If your not being specific and detailed with your question than you are confusing us and your self…
Twenty Eleven “2011” and Twenty Twelve “2012” are similar but anyway different themes.

1. I had 2012 theme.
2. I went to appearance >> header.
3. I uploaded a header image.
4. I went to my HOME website.
5. I did not see the header image that I uploaded.

What was the problem and how could I make it appear?

I think I am very clear now.

Have you modified the theme in any way? Did you try deactivating all plugins?

Oh yes, I have found that I have deleted before $header_image but now I recreate it.
Thank you all
