My web banner gest cut from both ends. how to adjust the banner size with respect to screen resolution on different screens?

regards

There is no elegant way of resizing the header images that are in the header folder since you have to account for the container they are in etc. You could add a new widget area in place of %image and then use a responsive slider in that area.

Thanks a lot lmilesw for quick response.

I am new to Wordpress... Can you explain how to do this exercise?

The instructions for creating a new widget area are described in the theme options under "Add new widget areas". Describing how to add and configure a slider is outside the realm of what we can cover in this forum. It would take way too much time to describe what all of that entails.

If you do a search for "wordpress sliders" you will probably fine a bunch of plugins. Then what I do is test them on my sandbox(test) site to get used to how things work.
