The maximum image width is determined by the resolution of the monitor Firefox is displaying on and how much of the monitor Firefox is using. Practically, this means you would need to allow for a width of up to 5120 pixels wide (for the next generation of 5k monitors).</p> <p>However, rather than creating a very wide image, a better approach is to use a narrower image with a transparent left edge so that it fades to the background color. For example, we could use this image:</p> <p><img src="/assets/img/documentation/themes/static-theme-single-image.4562e4db.png" alt="Single image"></p> <p>combined with a complementary background color, to create this effect in the header:</p> <p><img src="/assets/img/documentation/themes/simple-static-theme-preview.1b9c9857.png" alt="Simple static theme preview"></p> <p>See details about this theme in the <a href="https://github.com/mdn/webextensions-examples/tree/master/themes">themes</a> example <a href="https://github.com/mdn/webextensions-examples/tree/master/themes/weta_fade">weta_fade</a>.</p> <p>Obviously, you can still provide a single wide image if you prefer.</p> </div> </article> </section>   <section id="multiple-image-themes" class="module"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h3>Multiple image themes</h3> <p>As an alternative to creating a single image theme, you have the option to use multiple images. These images can be individually anchored to locations within the header, with the option to apply tiling to each image.</p> <p>Depending on the effect you want to create you may need to suppress the mandatory <code>theme_frame</code> image with an empty or transparent image. You would use an empty or transparent image if, for example, you wanted to tile a centrally justified image, such as</p> <p><img src="/assets/img/documentation/themes/static-theme-single-image.4562e4db.png" alt="Single image"></p> <p>to create this effect:</p> <p><img src="/assets/img/documentation/themes/static-theme-multiple-images.b3120107.png" alt="Multiple images"></p> <p>Here you specify the weta image like this:</p>  <pre class="language-js"><code class="language-js"><span class="token string-property property">"images"</span><span class="token operator">:</span> <span class="token punctuation">{</span> <span class="token string-property property">"theme_frame"</span><span class="token operator">:</span> <span class="token string">"empty.png"</span><span class="token punctuation">,</span> <span class="token string-property property">"additional_backgrounds"</span><span class="token operator">:</span> <span class="token punctuation">[</span> <span class="token string">"weta_for_tiling.png"</span><span class="token punctuation">]</span> <span class="token punctuation">}</span><span class="token punctuation">,</span></code></pre>  <p>and the images tiling with:</p>  <pre class="language-js"><code class="language-js"><span class="token string-property property">"properties"</span><span class="token operator">:</span> <span class="token punctuation">{</span> <span class="token string-property property">"additional_backgrounds_alignment"</span><span class="token operator">:</span> <span class="token punctuation">[</span> <span class="token string">"top"</span> <span class="token punctuation">]</span><span class="token punctuation">,</span> <span class="token string-property property">"additional_backgrounds_tiling"</span><span class="token operator">:</span> <span class="token punctuation">[</span> <span class="token string">"repeat"</span> <span class="token punctuation">]</span> <span class="token punctuation">}</span><span class="token punctuation">,</span></code></pre>  <p>Full details of how to setup this theme can be found in the <a href="https://github.com/mdn/webextensions-examples/tree/master/themes">themes</a> example <a href="https://github.com/mdn/webextensions-examples/tree/master/themes/weta_mirror">weta_mirror</a>.
