All the theme I installed on wampserver has slider header but when I activated it the theme does not show images only some content on the template and it was not organised.pls I need urgent reply from the house.

Still need reply

you will need to upload your own images to be used as the header slider

Once you have the slider plugin installed.. Activate the theme, edit the settings, add the images, then use either a shortcode to place the slider in your homepage.

Thanks for your response.will try it out

Also you can get premium themes for free and have no need for sliders plugins http://www.acegoals.com/get-wordpress-premium-themes-free/
