No, I looked at the image in my email client and find it's not readable in portrait mode. In landscape it is. <br />
<br />
I may have nothing to worry about, when I look at my blog in portrait and switch to landscape, the image grows. Will this happen using the same image for a header? Or do I need multiple images?<br />
<br />
Thanks.

I am pretty sure this is responsive. I think there will be no problem with the image being readable.<br />

I find the header image I had designed for my blog is not readable on an iPhone 6 when viewed in portrait orientation. Does WordPress have any way to display a different image based on device width?<br />

Is WordPress responsive?

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL for creating websites and blogs. Features include a plugin architecture, a template system and strong management, customization and search systems; through its dynamic presentation of content, webmasters have the flexibility to create websites easily.

A blog is a discussion or informational site consisting of discrete entries ("posts") typically displayed in reverse chronological order. Blogs can be the work of a single individual but more recently "multi-author blogs" (MABs) have developed, with posts written by large numbers of authors and professionally edited and "microblogging" systems help integrate blogs into societal newstreams.

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

Bootstrap is a free and open-source collection of tools for creating websites and web applications. It contains HTML- and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions. It aims to ease the development of dynamic websites and web applications. Bootstrap is a front end web framework, that is, an interface for the user, unlike the server-side code which resides on the "back end" or server.
