You can find more information how to include that in a wordpress theme here:

or here is a great plugin which can upload it for you:

Hello!

First of all, I can assure you that basically in most situations you can change a theme in WordPress with basically 3 clicks.

The best place to search for themes is inside the WordPress Theme Repository, which you can find on http://wordpress.org/themes/ or from inside your WordPress installation, in Appearance->Themes, and on the top the Install Themes tab. There you can set specific requirements, like color, column arrangement, features and so on.

Regarding the custom header, if you referring to the ability to put up your own logos and text, most themes have built-in settings which allow you to set those up easily.

What you are referring as easy to access from Android, is called site responsiveness. It is basically a function that detects the display size of a visitor, and decides what kind of design it shows to the specific visitor – the one designed for small screens, or the one for desktop computer display sizes. On the theme search page (inside your WordPress) this is called Flexible Width, so make sure you check that checkbox, when you are searching.

Sandly I cannot recommend you any specific themes, because there is so much of them. But if you need any help with any theme, just put post it here in the forums and I am sure there will be someone from us to help you.

I hope that I was somewhat helpful, if you have any additional questions, just ask them!

Hello!

Could you please provide a link to your site, and tell us what template are you using, so we could provide better help?

Depending on what theme are you using, here is what you could try: go to the page edition page inside the WordPress admin, and on the right side in most themes there should be a Page Attributes box, in that you can choose from so-called templates, which determines the layout of that particular page. On posts, there should be a Layout box. This is what it looks like on Responsive theme with pages:

and with posts:

I hope I was able to help you.

Hello!

The easiest way is to create a child theme, and make some css modifications there.

More info how to create a child theme you can find here:
http://codex.wordpress.org/Child_Themes

In your particular case, your child theme’s css file should contain this:

/**
 * Theme Name: Oxygen Child
 * Theme URI: http://alienwp.com/themes/oxygen/
 * Description: NOTE: 0.5 is a major update. Please backup your theme before updating and read the changelog.txt file for details. Oxygen is a minimalistic, mobile-optimized magazine theme with responsive layout. The main features include a featured content slider, custom front page template, 5 widget areas, and 3 menus.
 * Version: 0.5
 * Author: AlienWP
 * Author URI: http://alienwp.com
 * Tags: flexible-width, theme-options, threaded-comments, microformats, translation-ready, rtl-language-support, three-columns, right-sidebar, left-sidebar, custom-background, featured-images
 * License: GNU General Public License v2.0
 * License URI: http://www.gnu.org/licenses/gpl-2.0.html
 * Template: oxygen
 */

 @import url("../oxygen/style.css");

 /* =Theme customization starts here
-------------------------------------------------------------- */

#content {
    float: left;
    margin: 0 0 30px;
    width: 80%;
}

And of course don’t forget to activate the child theme.

You can fine-tune the width percentage value based on your needs, the original value was around 62%. However, you should check the theme’s responsiveness after the modifications.

I hope this helps, if you have any more questions, feel free to post them here.

Are you using some caching plugin? Because in that case you have to issue a cache rebuild for the database changes to actually appear.

Hello!

I suggest that you delete the default.htm file. The server needs to load the index.php file in order WordPress to run, and the default.htm overwrites that. If you try to open for example http://www.nricollection.com/contact/, you are getting the WordPress site you are missing.

If you have any additional questions, feel free to ask them.
